More than seven years after a Roswell man was gunned down during a botched robbery at his apartment, his killer pleaded guilty.

Kwame Dozier was given a life sentence this week for the January 2012 killing of 31-year-old Ladell Deon Crumpton, Channel 2 Action News reported.

The case went unsolved for years until Dozier’s conscience got the better of him, and he turned himself in at a New York police station in 2017, authorities said previously.

Crumpton was found shot to death outside his unit at the Concepts 21 apartment complex on Old Holcomb Bridge Road in what Roswell police said was drug and gang-related robbery.

“He always had a huge smile on his face,” Crumpton’s mother told Channel 2. “He was not threatening. He was not judgmental.”

Dozier took a plea deal and received a life sentence with the possibility of parole, meaning he’ll be eligible for release in 30 years.

Crumpton’s mother said while she isn’t sure she will ever get closure, she’s grateful that Dozier eventually came clean. She also said she had the chance to tell her son’s killer that at his plea hearing.

“The one thing we’ll always have in common is both of our hearts will be aching until the day we die,” she said, “yours because you can't see your children and mine because you took my son away from us and his children.”

While she’s glad Dozier his behind bars, Crumpton’s mother, who asked not to be named, said others involved in the case are still free.

“(Dozier) said there was another person that told him my son would be a good candidate to rob,” she said, adding she wants that person brought to justice as well.
