In addition to Burke, the lawsuit names several of Burke’s companies and managers, his mother and a live-in security guard.

Hernandez’s parents allege that these people “enabled Burke to isolate” Rivas Hernandez and facilitated his travel, housing and security.

Burke’s management company Mogul Vision and finance manager have previously denied knowing about Burke and Rivas Hernandez, the Los Angeles Times, external reported.

In July, a judge found enough probable cause for Burke to stand trial on the murder charge in the criminal case. At the time, the district attorney said he was weighing whether to seek the death penalty.

In a statement on Monday, which would have been Hernandez’s 16th birthday, her family demanded that Burke be subjected to execution.

“If the death penalty were activated, it would be perfect for this kind of human being, devoid of feelings and emptiness inside, and without conscience, who only caused pain to our daughter, our family, and the world that supports our precious daughter,” read the statement, released via the family’s attorney.

Burke again pleaded not guilty to the charges last week and has since parted ways with his celebrity defence attorney. He is now being represented by a public defender and is due back in court on 19 October. His trial has been moved to next year.

Deputy public defender Walid Kandeel has said that Burke was “entitled to a defence that takes his circumstances seriously and carefully examines the evidence”.

“We are committed to providing him with that defence,” he said.

His office did not immediately provide comment on the civil lawsuit.
