Bobby Brown Jr., a son of singer Bobby Brown and a stepson of the late Whitney Houston, has been found dead in Los Angeles, Fox News has confirmed. He was 28.

Law enforcement told Fox News on Wednesday that Robert Brown Jr. was found dead when they responded to a medical emergency call.

Foul play was not immediately suspected, law enforcement said, though no further details of cause or date of death were given.
