Police report a man was shot and killed after his body was found in Brooklyn late Sunday night.

The NYPD says the body was discovered at around 11:30 p.m. on the corner of Blake Ave. and Logan Street. Police have identified the victim as 28-year-old Andrew Cruz. According to officers, they found Cruz laying on the ground inside his apartment with a gunshot wound to the head.

Police say it was his brother who called 911 after he had gone to check on his brother after apparently not hearing from him. A gun was not found at the scene, and it’s still not clear what led up to the shooting or who the shooter is.

The investigation is still ongoing.
