Grammy-nominated singer Jubilant Sykes found dead with stab wounds at his home in Santa Monica, California, and his son was arrested on suspicion of murder.

Officers responded to a 911 call Monday night to find Sykes, 71, with critical stab wounds. Paramedics arrived and pronounced him dead at the scene, police said.

The victim’s son, 31-year-old Micah Sykes, was at the home and taken into custody without incident, police said. It wasn’t immediately known if he has an attorney.

Police recovered a weapon and the investigation was ongoing.

Jubilant Sykes was nominated for best classical album at the 2010 Grammy Awards for “Bernstein: Mass,” in which he performed the Celebrant role.

He appeared in the 1990 Metropolitan Opera production of “The Gershwin’s Porgy and Bess” in the role of Jake.

Sykes was artistic advisor for Orchestra Santa Monica, and he sang in and narrated some of the group’s performances, the organization said in a statement.

“Jubilant was a true inspiration—his artistry, generosity, and kindness touched countless lives,” said Roger Kalia, Orchestra Santa Monica’s music director.
