A 25-year-old Leavenworth man was sentenced Monday to 31 months in prison for his involvement with an August home-invasion robbery in south Lawrence.

Originally charged with aggravated robbery and being a felon in possession of a firearm, Darnell Warfield Jr. pleaded no contest in October to attempted robbery in a plea deal after he and co-defendants Amber Baker, 24, of Lawrence and Darvon Thomas, 18, of Leavenworth, robbed a home in the 3000 block of Havrone Way, according to court documents.

Victims told police that Warfield, Baker and Thomas went to the home to purchase marijuana before pulling guns on the home’s occupants, robbing them of an undisclosed amount of money and drugs, Lawrence Police Department spokesman Sgt. Trent McKinley said in August.

After the robbery, the three fled toward Leavenworth but were stopped in Leavenworth County and taken into custody, McKinley said. Officers recovered marijuana and two handguns from the vehicle, he said.

The victims were not arrested for any drug-related crimes in connection with the incident, McKinley said.

Warfield’s sentence of about two and a half years in prison is the highest possible for his attempted robbery conviction, according to Kansas sentencing guidelines for his criminal history. Warfield has 15 prior convictions “ranging from traffic to person felonies,” Douglas County District Judge Sally Pokorny said.

Warfield told Pokorny Monday that he was sorry for the role he played in the crime.

“I was in the wrong place at the wrong time,” Warfield said. “I want to say my apologies to the court.”

At Warfield’s request, Pokorny also lifted a no-contact order between Warfield and Thomas, who Warfield said was his cousin. Warfield asked for the order to be lifted Monday so he could attend classes in jail.

Thomas, who pleaded no contest to robbery in October in connection with the same incident, will be sentenced Dec. 15. Baker, who pleaded no contest in November to aggravated robbery, will be sentenced Dec. 29.
