Young's body was discovered in his home Monday after he fatally shot himself. He was 29.
Hundreds of mourners were expected to attend his funeral Friday afternoon on the lot where his show, "Rizzoli & Isles," is taped, TMZ said.
Production on the series is temporarily suspended while the cast and crew deal with Young's sudden death.
