. >> earlier this year dar la jackson a 27-year-old mother with no prior arrests was sentenced to six years in prison after pleading guilty to the voluntary manslaughter of navy officer zack yube. >> i'll commit you to the middle term of six years. >> the encounter between the two escalated when yube drove up alongside of her on his motorcycle and kicked the side of her car leaving a dent and shoe print. >> she couldn't believe he had done it. decided to follow him to get the license plate. >> another motorist captured a few seconds of the high speed chase and shortly after this clip cut off, disaster. >> what happens is he slows down. the driver doesn't react fast enough to that to gauge how much he's slowing down. so her nose of her car literally rolls up on to the back wheel of the motorcycle. >> now ensnarled, both the car and the motorcycle siding together for 315 feet before they became dislodged. yube hit the ground and dar la jackson ran over him. >> i won't see my daughter for a very long time. i deeply regret what happened. >> the country's roads and highways are increasingl
