A Houston man pleaded guilty to murder and was sentenced to 60 years in prison last week for killing his girlfriend and his father in 2021, Harris County District Attorney Kim Ogg announced.

“This was not an accident or mistake or anything other than an intentional double murder,” Ogg said. “The decisions that this defendant made have hurt two families immeasurably, and now he will likely spend the rest of his life in prison.”

Larry Britton, 41, was facing a charge of capital murder for shooting Joanne Rosas, 40, and 69-year-old Larry Britton Sr. on Aug. 7, 2021.

On the night of the shooting, Britton was up late and using PCP at the northwest Houston home where he lived with his father.

His girlfriend was also staying at the home, and Britton shot her in the house. He then chased his father out of the house and gunned him down on the street, which was captured on surveillance video.

When officers with the Houston Police Department responded to calls about the shooting, they found the 69-year-old victim dead outside. They went inside to find Rosas, who was still alive and able to tell them what happened.

She was taken to the hospital and died of her injuries about three weeks later. When she died, the charges against Britton were upgraded to capital murder for killing two people in the same incident.

On Thursday, Britton agreed to plead guilty to murder in exchange for 60 years in prison instead of facing the possibility of life without parole if convicted of capital murder.

Assistant District Attorney Phillip White, who is a chief in the Homicide Division of the DA’s Office, prosecuted Britton.

“These two people are gone forever because of the actions of this defendant—two separate families are still suffering because of what he did,” White said. “It’s good that both families were able to get justice.”

White noted that Britton cannot appeal the conviction or the sentence and must serve at least half of the sentence before he is eligible for parole.
