(McKinney, TX) -- A Collin County man is going to prison for a very long time -- more than a year after a man was gunned down behind a McKinney home.
Police said the victim, Rayshawn Williams, had multiple gunshot wounds and died more than two weeks after the incident.
Police learned that Williams' mother-in-law and her 18-month-old grand-daughter were inside the home at the time and that two armed men had rushed in demanding money.
Not getting money, one of them stole the woman's phone and then she heard gunfire when they went back out. The terrorized woman took the child and hid in the bathtub.
The next day in Dallas, police arrested Prince Haymer who held a phone later linked to the killing.
Detectives found Ring doorbell video showing Haymer firing three shots at the victim before escaping in the same car he was driving when he was arrested in Dallas.
In court, prosecutors showed a video of Haymer, recorded the night of the murder, showing him rapping and waving around one of the guns used in the killing.
Found guilty of murder, Haymer has now been sentenced to 75 years.
