A 30-year-old Akron man pleaded guilty Friday to murder and other charges in the death of his girlfriend last February.

Witnesses said they heard Brittany Littlejohn scream for help before the shooting.

Under an agreement with prosecutors, Duane M. Lucas pleaded guilty to murder, domestic violence, possession of heroin and having a weapon while under disability, which means he wasn’t permitted to have a firearm because of a previous conviction.

The murder charge includes a firearm specification. He also pleaded guilty to drug charges for an unrelated case.

Lucas faces life in prison when he is sentenced at 2 p.m. April 12 by Summit County Common Pleas Judge Tammy O’Brien.

Littlejohn, 31, was found shot to death on the front patio of her Romig Road apartment Feb. 21, 2017.

Akron police arrested Lucas the next day. He had a bag with a shirt and shoes that had Littlejohn’s blood on them.

There were several witnesses to the incident and Lucas’ DNA was on the gun used to shoot Littlejohn, according to a news release from the Summit County Prosecutor’s Office.

Lucas pleaded guilty Friday before Judge Amy Corrigall Jones because O’Brien was absent. O’Brien, however, will handle the sentencing.

Lucas’ original charges in the shooting case included aggravated murder, murder, felonious assault and domestic violence, all with gun specifications that carry mandatory prison time.

Lucas also faced drug charges for a 2016 case in which Summit County sheriff’s deputies responded to a domestic dispute involving Lucas and Littlejohn.

Deputies reported finding three bags of heroin and other drug paraphernalia in Lucas’ vehicle. The domestic dispute involved an argument and no violence or threats, prosecutors say.

Lucas was free on bond from the drug case when the shooting incident occurred.

For the drug case, Lucas pleaded guilty Friday to trafficking and possessing heroin.

Lucas is represented by Walter Benson and Jeff Laybourne in the shooting case and Scott Rilley in the drug case.

Jones ordered a pre-sentence investigation and a victim impact statement.

Prosecutors and defense attorneys will argue for suggested prison terms at the sentencing.

Several of Littlejohn’s family members were in court Friday, with many of them wearing purple ribbons, which are aimed at raising awareness about domestic violence. They declined to speak to a Beacon Journal/Ohio.com reporter.

Littlejohn’s friends and relatives held a march and balloon launch in her memory in May at Hardesty Park. Two women who are victims of domestic violence spoke.
