Sources say the gunman in a deadly apartment shooting in the Bronx has died.

Jorge Vega was in critical condition after shooting himself in the head last Wednesday.

Police say he shot himself after killing his girlfriend Susan Trivino, and her daughter, Suchari Guzmán, in their Soundview apartment.

Sources say Vega was recently suspended from his job as an MTA bus driver for being drunk, and then resigned.

NY1 is told Trivino had broken off her relationship with Vega the day before the shooting.

She was also an MTA driver.
