Wild footage shows a California man accused of decapitating his parents and their dog being shot multiple times by cops — and then belting out Tina Turner’s “What’s Love Got to Do With It” as he lay bleeding on the ground.

Orange County sheriff’s deputies found Joseph Gerdvil on a street outside the San Juan Mobile Estates while responding to a grisly murder scene in San Juan Capistrano on July 9.

They had just found the headless bodies of his parents — 77-year-old Ronald Gerdvil and 79-year-old Antoinette Gerdvil — along with their mutilated dead dog in their mobile home, police said.

One of the heads was displayed on a counter, according to CBS News.

Gerdvil was spotted a short time later after allegedly attacking a maintenance worker, authorities said. When police approached him, he was covered in blood, babbling incoherently and threw a heavy shovel at them.

When a deputy ordered him to stand down, Gerdvil charged and the officer unloaded five shots at him from about 10 feet away.

The first three bullets seemed to have little effect on the 41-year-old, but after the fourth, he dropped to the ground and blood started pouring from his wounds.

Within moments, responding officers began tending to Gerdvil, and his already erratic behavior began to take a turn for the truly strange.

“I love you … I’m sorry you’re gonna have to die,” he said at one point.

“Just finish me off,” he said moments later. “Put one in my head, please. I beg of you.”

Cops, meanwhile, rushed to cover the wounds and slow the bleeding until medical help arrived.

Gerdvil then started crooning love songs.

“What’s love got to do with it, got to do with it? What’s love but a second-hand emotion?” he sang from the 1984 Tina Turner hit.

Gerdvil next pivoted to Stevie Wonder.

“I just called to say I love you,” he sang from the track of the same name, also from 1984.

The suspect was rushed to a nearby hospital, where he was stabilized.

He faces two counts of homicide over the deaths of his parents.
