Los Angeles County Sheriff's homicide investigators continue to examine the death of former NFL defensive tackle Kevin Johnson, a spokesperson told USA TODAY Sports on Jan. 23.

Investigators have released limited details on the death of Johnson, 55, who was found shortly before 8 a.m. PT Jan. 21, near a homeless encampment roughly 10 miles east of Los Angeles International Airport. In a release, the sheriff's office said that deputies located an unconscious adult male, later identified as Johnson, suffering from head trauma. He was pronounced dead at the scene.

"Unfortunately it appears he was homeless," Los Angeles County Sheriff's Lt. Steve De Jong told Newsweek on Jan. 22. "It looks like he was probably living there."

The sheriff's office has not released additional information about its investigation, including the status of its search for a suspect.

The Los Angeles County Medical Examiner on Jan. 22 cited "blunt head trauma and stab wounds" as Johnson's cause of death and listed his place of death as a homeless encampment.
