A worker found the body of a man floating in the lake at Centennial Regional Park Wednesday morning in Santa Ana, police said.

Officials were called to the scene at around 9:45 a.m. to the park after the worker found the dead man, said Cpl. Anthony Bertagna of the Santa Ana Police Department.

Homicide detectives and the coroner reported to the scene, which had been roped off to the public, where around 100 onlookers had gathered.

“At this point there are no obvious signs of trauma but we’re still investigating,” Bertagna said.

Details about the body and how it ended up in the lake were not immediately known .

The man did not have an identification and determining his name was first priority in piecing together how he ended up in the water, police said.

By noon, the body had been taken by the coroner and the lake reopened.

Though there were no apparent signs of foul play, investigators said there are many unanswered questions.

“Did this man have an accident? Was there a crime committed here? The first step is finding out who he was,” Bertagna said.

An official cause of death will be determined later this week by the coroner.
