her arrest, the teen seems more distraught about her jewelry than her victims. it was supposed to be a fun night out for mackenzie churilla with her boyfriend dominic russo and his friend davian flanagan in strongsville, ohio. but in the overnight hours, with mackenzie churilla behind the wheel of this toyota camry, it would all turn tragic. everything appeared to be normal as cameras show their vehicle approached the intersection. after the car makes a right turn, it starts to move at full speed, 100mph, then slamming into a building. this is the scene as police arrive. true crime news obtained hours and hours of body cam video. the front of the car completely smashed in. the three friends are caught in the twisted metal and destruction. >> oh my god. >> i don't even know how to

but as investigators start to piece together what happened that night, they find marijuana in the car. and tests reveal that mackenzie had a thc level above the legal limit. they start to question what was going on while mackenzie was behind the wheel, trying to determine whether this was an accident or a deliberate act of murder. >> hook deivy 360. don't you guys have about one big crash. and friends start showing up at the police station saying they noticed something on the tracking device, life 360, which can calculate how fast someone is traveling. >> she hit the gas, the floor. and it shows you that they literally hit the gas right when they got into that area. they were driving fine for like 15 minutes, right? palve all of a sudden you drive good for 15 minutes. you drive bad for like two minutes. >> they say the data on the app says the car never slowed down before hitting the building, and

they tell police about what they call a toxic relationship between mackenzie and dominic russo, her boyfriend of several years. >> there's lots of people that have come up to me and said they've always fought like everybody. like i can probably do a lot of witnesses to say that. >> they say davison only asked for a ride home that night and was in the wrong place at the wrong time. police learned of a previous incident where mackenzie threatened to crash her car while her boyfriend was a passenger. >> i'm detective jesús. i'm the one who's been investigating the crash. >> several months after the crash, mackenzie is arrested. >> you're under arrest for aggravated murder. times two. okay. nobody's going to ask you any questions. nobody's going to bother you. can i have your feet, please? >> could you please be careful taking this one off so it doesn't break the bracelet, please? >> you got it. you got it. you want my cuffs? no. thank you. you got it. >> police say the toyota event

data recorder showed that mackenzie deliberately accelerated into the building. and she never once tried using her brakes. her parents arrived to the police station as she's being booked. >> okay. >> well, i still need. to speak to my daughter so she understands. what? her not to say anything to you guys. >> she is 18 years old and she could speak to that. >> but she's a dumb 18 year old that just turned 18. and you guys are not dumb. all all the kids nowadays are dumb and these guys are going to take advantage. she's not allowed to speak to you guys. i'm telling you that. >> her attorney can call us. >> mackenzie is booked and charged with two counts of murder. she would later be found guilty in a bench trial. >> and despite. >> pleas from her parents in court for leniency, she is sentenced to 15 years to life in prison with the possibility of parole. davian flanagan's father, posting this on facebook saying that we do not seek vengeance, only justice for our son who was nothing more than an innocent passenger looking for a

welcome back. it is a case that puzzled authorities in louisiana for years. and they need your help. at first, it appeared that nanette crennel, the wife of a local fire chief, had died in a tragic house fire. but investigators would find something much more sinister at play when they sifted through the ashes. >> oh my god. >> the thick. >> black smoke from the raging fire turns day into night. >> it is fully engulfed from the second we pulled up. the heat so intense. all that's left of the house is a concrete slab. >> there was nothing of the house that had any kind of chance of being salvaged. >> and buried beneath the rubble. the charred bodies of a dog, two cats, and the woman who was so devoted to them, she was, ironically, the wife of the fire

chief. >> they made a. a wall of people standing shoulder to shoulder, so that i couldn't see them move her. >> and he's the first responder who arrives to find his own house on fire. >> come on. come on, let's go. >> then realizes he's lost everything. >> i knew at that moment that they had found her. they didn't even have to say a word. >> how did nanette crennel die? did she try to rescue her pets and was overcome by smoke inhalation? was it suicide by fire, or was that blaze intentionally set to cover up a murder? >> it just made no sense that in the middle of the day here, she would have died in a fire. >> nanette crennel grew up along the bayous of new orleans. >> nanette. >> she was a. >> very sweet. >> caring person. >> she had a little bit of a

feisty side. >> to her. nanette and i met our freshman year. we just kind of clicked, and she was. >> this fun. >> kind person. >> who you just love spending time with. >> but the person who nanette spent the most time with is the one who captured her heart. steven crennel. although he was already married when they met, he soon divorced and married nanette, who worked as a preschool teacher. >> absolutely loved being with the kids and was one of the most sought after teachers in this area. she has a huge heart. she has tremendous compassion for animals. >> so when nanette finally retired, she spent her days raising animals on their massive 100 acres in lacombe, louisiana. she also passed the time practicing her hobby shooting. >> it was something that we could walk out our back door and do on a routine basis, and she didn't go anywhere without at

least one gun with her. >> and nanette had a lot of guns for the house, the car and her purse. she had everything to live for her animals, her guns, rural life for this loving couple was good until that fateful day. >> i got a phone call from my cousin and he was telling me that my house was on fire. and at that second, i hung the phone up, ran out with my chief of training, and we jumped in my department vehicle and started driving to the house. i was calling her cell phone, i was calling the house phone and everything was going straight to voicemail. >> in this dramatic footage of the very moment, steven can be seen rushing to his own home as it was burning to the ground. >> when we got to a point that we could see the home, it was from one end to the other. it was fully involved. >> and then the worst. >> i knew they had found her at that time. >> but when the coroner takes nanette's charred body to the morgue, a shocking discovery.

the fire didn't kill nanette. it was something far more ominous. >> the coroner's. >> office and our. pathologists here discovered. >> a bullet hole in her head. >> her beloved animals were also shot. but who pulled the trigger? nanette. or a cold blooded killer. >> i knew it. i knew. somebody did this. she didn't just die in that fire. >> and in the charred remains, investigators find a gun next to nanette's body. >> unfortunately, due to the hot temperatures of this fire, we weren't able to pinpoint whether the ballistics that matched. >> the coroner's office reports the death as a homicide, not a suicide. and then another shocking conclusion. the sheriff says it appears the fire was ignited to cover up nanette's murder. >> at this point, yes, the fire was intentionally set.

of violence. and of course, the chief steven was our first person of interest. >> the fire chief nanette's husband, steven. >> i was never offended or upset when the police were investigating me. i cooperated with everything. >> steven offered to take a polygraph, and the sheriff admits he passed. >> i can go to sleep every night knowing i had nothing to do with this. >> he has been cleared at this time. of course, that could change during the course of this investigation, but right now we're pretty. we're pretty clear he was not involved or there at the time of her death. >> leaving it all one big mystery. but as the investigation reveals, someone may have had it out for her. >> she didn't feel safe. >> turns out, 17 days before the horrifying incident, nanette emailed her father. >> she said she was being followed. >> sadly, though, her father has since passed away. at the time, he shared this image of a

mystery man lurking outside her front gate. >> she also said that she had found a knife and cigarette butt on the property, and she said somebody has come onto the property. >> in the email, nanette wrote this caption this was the day i got out to get the mail and looked up and this man was walking towards me. he just looks creepy. the man remained unidentified and nothing apparently came of it, but nanette was prepared. >> she had one gun in her purse, one gun, a different gun in her car, another gun in the house. plus she had a remington 20 gauge home defense shotgun. and i know there was an ar 15 because she said, this is my baby. >> and best friend. lowry randorf says nanette amassed the firepower to protect her from someone she knew. her brother in

law, steven's brother, brian crennel. >> she never. >> felt safe, not even in her own home. >> we asked steven if he thought his brother would harm nanette. >> i did not believe it, but when something like this happens, you have to think that that's a possibility. because if that's the case, he or anybody should pay for this. >> brian has a long rap sheet with 36 arrests for petty crimes. that, along with those alleged threats, made him a person of interest. >> he was a second person of interest, and his alibi checked out. >> nanette revealed her fears about brian in a series of facebook exchanges to lowry, saying the night he got arrested, he told steve he was going to get out and kill us and then himself. >> he would threaten. >> her because. >> i think he felt that she was kind of sticking her nose in his family business where it didn't

belong. >> steven says the reaction could be related to an incident a few years before nanette's death. >> he was drinking and the police wound up arresting him that evening, and he went to jail for about a year. and i know that he felt because nanette did go with me. he felt that we bear some responsibility for that, and he had a hard time forgiving us for that. >> his alibi was as ironclad as the jailhouse ankle bracelet he was wearing. brian was on house arrest at his mother's home, and security video places him there the day of the murder. the sheriff says brian cooperated with investigators, and he has never been charged with any involvement in nanette's death. with brother steven's help, he also took our call to comment on whether he and nanette had any fights. >> no, not with nanette. no. my brother, i might have had a fight. i mean, i've been fighting with him since i was

born, but with diane, i ain't never had a cross word. and she never had a cross word to me. >> we asked brian if he had any theories about nanette's murder. >> i would not have a clue. you know, it'd be like snowing in louisiana is a one. >> time thing. >> every now and then, you know? >> yet investigators stand by the assessment that nanette's death was a homicide, and everyone still needs answers. >> i don't know what to think, because that's not where she was found. does not make sense to anything. >> i don't see it as a random act of violence. this fire. whoever, whoever set the fire knew what they were doing. it is a homicide that did occur, and that's what we're going to handle it. >> i want to know what happened. i can't wait to look at that person. and. just know who and why. >> those are questions police still can't answer, and they

need the public's help. remember the mystery man seen outside her front gate in an image shared by her late father? he remains unidentified. and for now, nanette crennel's murder remains a true mystery as well. >> we just need that one piece, that one piece of information that we're still missing. >> if you have any information about nanette reynold's murder, please call the greater new orleans crime stoppers at (504) 822-1111, or contact our tip line at (888) 845-7555. we'll be right back. >> audi below the belt. nobody likes that. >> it's time you. >> discovered looney. whole body deodorant for pits, privates and beyond. looney was developed by an ob gyn who, you know, knows our body chemistry. it works like magic. you got to go to their website and try it for
