Law's body was discovered by a maintenance man Saturday morning. Her employer, A. Charles Peruto Jr., a prominent Philadelphia lawyer, described Law as his girlfriend but said he spent Friday night in Avalon, N.J., The Philadelphia Inquirer reported.
"Julia was a beautiful, caring free spirit hippy, who I was blessed to have known," he told the Inquirer in a text message Sunday. "Words can't express how sad I am to finally have met someone who I believed truly loved me."
The cause of death had not been determined Monday. Authorities have said toxicology test results may be available Tuesday afternoon.
Investigators have said there were no obvious signs of foul play.
A friend told the Inquirer Law and other friends had been planning an evening at the Capital Grille for her birthday.
