Update: According to charging documents, 14-year-old Keyshaun Mason was killed as he attempted to help his mother, who was being held at knifepoint by her boyfriend.

Lakisha Jenkins and her live-in boyfriend, Sean Crawford, were arguing through the night. When Mason and his brother attempted to come to their mother’s aid on Monday morning, Crawford grabbed a knife and barricaded himself and Jenkins in their bedroom, police said. The boys managed to make their way inside the room in an attempt to persuade Crawford to leave. Instead, he stabbed Mason in the chest and his brother in the shoulder, according to the documents. Crawford then fled, but was apprehending by officers responding to the call.

“We never thought that would happen,” Jenkins told The Washington Post. “You’re sad that your child’s life was taken away.”

A high school freshman was fatally stabbed on Monday morning, and his mother’s live-in boyfriend has been arrested in the case, Prince George’s County police said. The boy’s 18-year-old brother was also taken to the hospital with stab wounds.

Sean Crawford, 48, has been charged with first-degree murder in the death of 14-year-old Keyshaun Mason, as well as attempted first and second-degree murder for the attack on his brother. He is expected to be held without bond.

Police believe that the attack stemmed from an argument in an apartment in the 600 block of Audrey Lane in Oxon Hill, Maryland.

“It was like a football field of people fighting under me,” neighbor Alexis Black told NBC4. “It was really, really loud.”

Police responded at 7:25 a.m.; Mason was pronounced dead at the scene. He was a freshman at Potomac High School.
