Dustin Walker, who after three trials was found guilty of fatally shooting a 39-year-old Lawrence man in 2014, was sentenced Friday to life imprisonment.

Walker, 31, was found guilty of first-degree felony murder, which is a killing committed during the commission of a felony, on March 11. He was found guilty of aggravated burglary in a previous trial a year earlier.

In all, Walker was sentenced by Douglas County District Court Judge Paula Martin to life imprisonment with the eligibility of parole after 20 years for the felony murder charge, and an additional 130 months in prison for the aggravated burglary charge, Cheryl Wright-Kunard, assistant to the Douglas County District Attorney, said in a release. The two sentences will run consecutively.

Walker was accused of breaking into the duplex of Patrick Roberts in the early morning hours of March 8, 2014, with another man — Archie Robinson — to steal money and marijuana. During the incident Walker shot and killed Roberts.

Robinson was found guilty of both first-degree murder and aggravated burglary in March 2015. He was sentenced to life in prison without the possibility of parole for 20 years for the murder charge and 57 months in prison for the burglary charge.

If released from prison, both Walker and Robinson will have to register as violent offenders for 15 years, the release said.
