A man accused of killing a woman in his Williamsburg apartment last night jumped to his death off the roof of his apartment building, police said.

 

Cops responded to a 911 call of an unconscious woman at an apartment at 325 Roebling Street just after 10 p.m. last night.

 

When officers got there, they discovered a 29-year-old woman unconscious and unresponsive in the bathtub of the apartment, bleeding.

 

Witnesses told them they saw the suspect, a 25-year-old black man, flee the apartment towards the roof. They followed him up to the roof and watched him jump off the building, just under the Williamsburg Bridge.

 

When EMS workers responded to the scene, both the man, Efriam Gabourel, 26, and the woman, Liliana Belfor, 29, were pronounced dead.

 

Gabourel lived in the Roebling Street apartment. Belfor lived in the Midwood neighborhood of Brooklyn. The two were dating, said police.
