Jubilant Sykes — a Grammy-nominated opera singer — was stabbed to death inside his L.A. home Monday — and his son was arrested in connection with the murder, according to police.

Cops said they responded to an “assault in progress” Monday night at Sykes’ Santa Monica home after receiving a 911 call from an unidentified person.

When officers arrived, the 911 caller directed them inside the residence, where they found Sykes with “critical injuries consistent with a stabbing,” police said. Sykes later died at the scene.

Police said his 31-year-old son, Micah, was present inside the home and arrested in connection with the murder, then booked into the L.A. County jail for suspicion of murder. He’s being held on $2 million bail.

At least one person is dead and another person is wounded in critical condition after a campus shooting at Kentucky State University Tuesday afternoon.

Local outlet WDRB-TV reports a suspect is in custody following the incident, which took place at a campus dorm.

According to the outlet, officers arrived at the campus in Frankfurt, Kentucky just after 3:30 PM Tuesday. The school was immediately secured and locked down.

Kentucky Gov. Andy Beshear posted about the incident, writing, “We are aware of a reported shooting at Kentucky State University in Frankfort. At this time, we are aware of some injuries. We will share more information as available. Law enforcement are on scene, and a suspect has been arrested. Let’s pray for all those affected.”

“Jimmy Neutron” star Jeff Garcia is in the hospital … and it doesn’t sound good.

Family sources tell us Jeff is currently hospitalized in Southern California, but it’s unclear what is ailing him.

We’re told Jeff was previously hospitalized around November 20 with pneumonia … but he recovered and was discharged a few days later.

His “Jimmy Neutron” character even got his own spinoff show, “Planet Sheen,” in 2010, and Jeff did voice work in 26 episodes.

Jeff’s also a standup comic … and he had been doing comedy work as recently as November … a couple weeks before he wound up in the hospital.

He’s only 50 years old.
