Dustin D. Walker in Douglas County District Court during his first trial in the death of Lawrence resident Patrick Roberts.

On Monday — and for the third time — Dustin D. Walker entered Douglas County District Court to stand trial for the 2014 slaying of Patrick Roberts.

Prosecuting and defense attorneys questioned a pool of 42 prospective jurors. Throughout the day the attorneys asked about the pool members’ employment, family, ethics and stances on issues like marijuana and gun control. After nearly six hours 14 jurors, including two alternates, were chosen from the pool to serve as the jury for Walker’s trial.

Throughout the process Walker, 31, sat silently, dressed in a blue dress shirt with a tie.

Police say Walker and another man, Archie Robinson, broke into Roberts’ apartment on March 8, 2014, to steal cash and marijuana.

Once inside the apartment, Robinson pointed a gun at Roberts’ son and Walker shot Roberts in the chest, killing him, police said. Roberts was 39 years old.

During his first trial in February of 2015, Walker faced felony charges of aggravated burglary and felony murder, which is a murder without premeditation during the commission of a felony. The jury found him guilty of aggravated burglary, the underlying felony, but could not reach a decision on the felony murder charge.

Walker was tried again, and in December of 2015 — facing a felony murder charge — a jury once more could not reach a decision on the charge.

Robinson meanwhile was found guilty of both first-degree murder and aggravated robbery in Roberts’ death during his own trial in March 2015. He was given a life sentence without the possibility of parole for 20 years.

With a jury selected, Walker’s third trial will begin at 9 a.m. Tuesday.

Walker remains an inmate at the Douglas County Jail in lieu of $1 million cash or surety bond.

Walker has several prior convictions within Douglas County. In 2008 he was convicted for aggravated battery and he was convicted of two charges in 2012 in relation to operating while intoxicated and fleeing a law enforcement officer.

He was acquitted in 2011 on charges connected to his alleged role in a December 2010 shooting at South Pointe Apartments, 2310 W. 26th St. In that case Walker was charged with attempted second-degree murder and possessing a firearm as a felon after Darrick Dew was shot during a large party at an apartment.

In 2008, Walker was suspected in a robbery at a Lawrence apartment that resulted in a man being shot in the leg. But in 2011, Douglas County prosecutors dismissed the case before it went to trial. Douglas County District Attorney Charles Branson said afterward that both the victim and witness were unable to recall the incident, precluding prosecutors from pursuing the case.
