blaze telling her not to come to the house. >> amy is in bed sick tonight and she was sick this afternoon and vera offered to stay and help her out so she's going to stay the night here. her phone died and i don't have a charger that fits her phone. so i don't know if you can tell anybody that would be worried about her that she's just going to be here with us tonight. >> reporter: thursday the morning of the fire the housekeeper receives a text message from amy telling her not to come to the house. >> they say i want to make sure you do not come today. i don't understand why. god saved my life. >> reporter:. also telling abc news that the husband then went to the home looking for his wife because he hadn't heard from her. banging on the front door, hearing noises coming from inside. then receiving a call saying his wife is staying the night.

tuesday in washington, d.c. the chief of police hinting at the detective work going on out of camera view. >> there's certainly a huge element talking to people. but a large part of it is puzzle piece after puzzle piece. there's digital evidence that has to be recovered, lots of videos to be reviewed dna and other forensic evidence that has o to be gathered. >> there's a number of way to look at these cases. people who dealt with robbers, there are groups of people that do home invasions. they'll look at the phones of the husband, the wife, the home line, both housekeepers, they will look at their computers to see if they have had any traffic that would lead them to somebody else. as you pull all of that information, there will be little streams of information that come out. >> reporter: police were carrying items out of the house but they are keeping a tight lip

about what was in the evidence bags. >> did the bad guys take anything? it's relevant to find some forensic forensic link to them. >>. we'll have an arrest tomorrow. it's premature to comment. there's still some more evidence gathering to do. >> reporter: with the potential for evidence recovery to take more than a week, answers for neighbors can't come soon enough. i'm ryan smith in washington, d.c. up next bull riding light e shows, this pastor will do just about anything to get people in the door. melissa mccarthy still bringing the heat. a new action comedy call canned "spy." she opens up about her career and about having jude law as her love interest. about a biologic...

at a time when polls show organized religion is on the decline in america, tonight you'll meet one pastor going the extra mile to fill the pews. they call him the cowboy pastor. he delivers sermons on horse back rides a bull in the church and that's not the half of it. there's been a little bit o of controversy and so here's abc's david wright. >> the bible says we have an adversary called the devil. >> reporter: speak of the devil and his horns appear. real horns inside a real church. this is bone crusher. that's preacher lawrence bishop preparing to dig in his spurs.

a leap of faith riding this bull for jesus. >> i'm not going to try to preach from the bull's back. >> i did do a sermon off a horse with a head set microphone. but on a bull it could have to be an 8-second sermon. >> reporter: he and had his wife have two sons. bishop is the pastor of solid rock church in monroe ohio. the one with the 52-foot statue of jesus facing i-75 nicknamed hug-me jesus because of his pose. welcoming new believers is what the bull riding thing is all about. >> the bible said compel them to come in. so that's what we're doing. didn't say how to come them. i don't have very many talents other than riding things that bucks or playing music.

i use both to spread the gospel. >> the bat toll win souls is fiercely competitive. 23% of the population is unaffiliated with any organized faith. so preachers are pulling out the stops, mixed marshal arts, fitness and christian rock. the solid rock church has been breaking the mold for 40 years now. founded by lawrence bishop senior and his wife darlene. >> solid rock is fun. people love to come to church. it's an exciting place. >> reporter: the bishops started off in the horse business. the lb ranch, one of the four most breeders of the quarter horses. she lives in the ravish ranch house overlooking the horse farm. >> help yourself. can i get anybody anything? >> cowboy christians in every

way. >> thank you for this day, thank you for this food. keep everyone save tonight. in jesus' name i pray, amen. >> we call our church an extreme church because we don't do anything just normal. my husband used to say the seven last words of a dying church is never seen it done this way before. >> when your son said she's going to build the ring in the church, what did you think? >> i thought he was crazy. >> crazy seems to be a daily occurrence here. our cameras were rolling as one of the horses ended up in the swimming pool. he was try inging to walk across the cover when the cover gave way. now hopelessly tangled, the horse at risk of drowning. pastor bishop appears to walk on water like the savior himself. >> baptized the horse. >> already sold to another preacher. so i told him he's already been

baptized. >> i'm the preacher's wife. >> she's also an artist who launched her own business designing pulpits and crosses. she welds them herself. >> contemporary art is kind of my thing. steel and grinded metal, stuff like that. >> this whole family it seems like it could be a good reality show. >> after the horse fell in the pool yesterday, i would have to agree with you. >> reporter: the church is not without controversy. for instance, there's a bizarre urban legend that lawrence bishop sr. first made his fortune smuggling cocaine in the horses and the giant jesus statue is packed with white powder. >> any truth there? >> sooezero. my dad did work and church. >> the congregation is 3,000

strong one of the most racially mixed churches you'll ever see. half the crowd is black. everyone is welcome. not everyone. the church is very outspoken on the issue of same-sex marriage. >> we love homosexuals. i had an uncle that was homosexual and died of aids but we do not agree with homosexuality because the bible is against it. we have to -- >> the bible is also against eating shellfish. >> you're talking about in the old law. >> i don't remember jesus talking about homosexuality? >> it's in romans and many times jesus mentioned marriage in the bible, it was always a man and a woman. >> reporter: the ministry constantly coming up with creative ways to connect. >> we're doing everything we can. >> reporter: the church operates a home for troubled women. the hope over heroin targets young people struggling with addiction.

>> he that win earth souls is wise. the bulls are going to attract people who would never set foot in a a church. >> he was a professional bull rider, but that was years ago. >> what are you most worried about? >> probably pulling a groin muscle. my 48-year-old body is not like my 28-year-old body. >> reporter: among the friends who have come along to bare witness and lend moral support is one of the top bull riders in the country. >> there's no such thing as an atheist in a fox hole, you get that around dangerous activities as well. >> reporter: the church is packed. a lot of new faces here. finally, the moment of truth. pastor lawrence has got to hang on for 8 seconds. he lasts about 3.

everyone in the house is saying their prayers at this point. finally, battered and bruised, the cowboy preacher climbs back up to safety. and in a truly impressive example of grace under pressure even manages to give his sermon having just been stomped and gored. >> be baptized. >> reporter: when it comes time for the altar call, the response is huge. 300 or so new believers ready to be baptized. the pastor truly thankful. >> it was with the wild beasts. >> what happened at the altar and to the kingdom of god is worth it. >> reporter: an unconventional approach fought with danger but at the solid rock church it seems to be reaping results. i'm dade wright for "nightline"
