A tragic incident unfolded in northern Ohio, where a man allegedly murdered his girlfriend before also targeting her two sons. Authorities have identified Gregory Tillman, 38, as the suspect, and he now faces multiple charges, including murder, assault, and domestic violence, as well as charges for possessing weapons illegally, according to Summit County jail records reviewed by Law&Crime.

The fatal encounter occurred over the weekend at the home of 44-year-old Rebecca Guthrie, located on the 500 block of Miles Avenue in Akron. Guthrie was in her residence with her two sons and Tillman when an argument erupted between the couple late Friday night and into the early hours of Saturday morning, as recounted by one of her sons.

“I heard my mother and her boyfriend arguing, but they argue all the time,” shared 18-year-old Marquis Terrell in an interview with Cleveland-based CBS affiliate WOIO. “I didn’t think it was anything serious.”

However, the argument escalated into a violent confrontation, leading to the tragic events that followed.

Then, the scene turned violent.

“I heard gunshots, I heard yelling and screaming, she was yelling ‘stop’ and everything,” Terrell went on. “And then he ran upstairs and shot my brother.”

The bullet grazed the 25-year-old son’s head, authorities said. Then, Tillman allegedly turned the gun on Terrell.

“He tried to point the gun at me and shoot me, but it clicked twice. And then he tried to shoot my brother,” Terrell went on. “My brother wrestled the gun out of his hand, I tried picking up the gun and shoot him with it; it didn’t do anything so he ran, he fled.”

Terrell called 911 and reported what was happening to law enforcement.

“I need help, I need help,” he said. “My mom’s boyfriend … just shot, he shot my brother.”

At about 2:10 a.m. on Saturday, Akron police officers arrived at the home and “discovered the victim lying on the living room floor with multiple stab wounds and a gunshot wound,” which was reportedly to the head. She was pronounced dead about 20 minutes later, the Summit County Medical Examiner’s Office said.

Officers found Tillman down the street a short time later. He was booked into the Summit County Jail on no bond. The injured son was in the hospital recovering from his injury as of Monday, WOIO reported.
