The Baltimore officer who fatally shot a woman after an hours-long standoff was also involved in a shooting in 2007.

In a statement Thursday, the department identified the officer only by his last name, Ruby. The officer has been with the department for 16 years. Police Chief Jim Johnson had previously declined to identify the officer who shot 23-year-old Korryn Gaines, citing threats against the department.

Gaines, who was African-American, was killed on Aug. 1 after pointing a shotgun at officers attempting to serve an arrest warrant in Randallstown, a suburb of Baltimore. Her 5-year-old son was with her at the time. He sustained an injury after being grazed by a bullet.

Gaines’ death led to protests affiliated with the Black Lives Matter movement.

Baltimore police spokeswoman Elise Armacost said that in 2007, Ruby was one of two officers who shot and killed 24-year-old Adam Benjamin Rothstein after he pointed what turned out to be a pellet gun at the officers. Armacost said officers received a call on Aug. 19 for a suicidal man who’d told the 911 dispatcher that he had guns, knives, pepper spray and a Taser.
