A 25-year-old man city police believe fatally stabbed his girlfriend Thursday died hours later after hanging himself in Catonsville.
Brandon Jerome Nowlin, whose last known address was in Halethorpe, killed Rebecca Ann Coughenour, 23, of Baltimore, inside her home Thursday, police said.
Police categorized the killing as an act of domestic violence. Nowlin and Coughenour had been in a relationship for several years, officers said. Police said the couple had a "prior history of domestic violence."
Investigators responded to the 200 block of Atholgate Lane in the city's Ten Hills neighborhood about 12:30 p.m. after a 911 caller requested help and found the woman unresponsive and suffering from multiple stab wounds, officers said. Coughenour was pronounced dead at the scene.
As detectives were conducting their investigation, they received word that Baltimore County police were searching for a man possibly linked to the killing in the 5500 block of Baltimore National Pike in Catonsville. At 4:21 p.m., Nowlin's dead body was found there by emergency crews inside a vacant office building, Baltimore County police said.
Police categorized Nowlin's death as "apparent suicide" by hanging.
