A Maryland man stabbed his girlfriend's 14-year-old son to death and injured the teenager's brother, Prince George's County Police say.
Keyshaun Mason, who had just started his freshman year at Potomac High School, died Monday after he was attacked inside his own home.
Sean Crawford, 48, stabbed Mason and his 18-year-old brother inside the home they shared on the 600 block of Audrey Lane in Oxon Hill, Maryland, the preliminary investigation shows. Crawford is the live-in boyfriend of the brothers' mother, police said.
Officers were called to the scene about 7:25 a.m. Mason was pronounced dead on the scene and his brother was treated and released. Neighbors said they heard yelling.
"It was like a football field of people fighting under me," neighbor Alexis Black said. "It was really, really loud."
"Preliminarily, our detectives believe that this incident stemmed from some sort of argument," Officer Nicole Hubbard said.
Officials at Potomac High School shared news of Mason's death with stunned students at the end of the school day Monday. Grief counselors were available.

"He was a nice kid. He was friendly with everybody," Chardonnay More, 14, said. "My best friend is gone."
"He was so sweet and he had a future," Black said.
Crawford will be charged with first-degree murder and attempted first- and second-degree murder, police said. He is being held without bond.
