A security employee working at Michael Jackson’s home has been identified as the person who made the 911 call after the pop star was found not breathing and unresponsive in his bedroom last Thursday, June 25.

According to Access Hollywood, the caller was Alberto Alverez, who is not speaking to the media per a confidentiality agreement he signed prior to his employment.

“We have a gentleman here who needs help, he’s not breathing, we’re trying to pump him but he’s not breathing,” Alverez told emergency services on the call made last week.

Jackson later died at UCLA Medical Center. He was 50.
