MIAMI (AP) - A Florida medical examiner says only marijuana was found in the system of a Florida man shot while chewing another man's face.

The Miami-Dade County Medical Examiner's released the toxicology results Tuesday on 31-year-old Rudy Eugene. Lab results found marijuana in his system, but not any other street drugs, alcohol or prescription drugs.

The department has ruled out the most common components found in the street drugs known as bath salts. An outside forensic toxicology lab also confirmed the results.

Surveillance video captured 65-year-old Ronald Poppo being attacked by Eugene on May 26. A police officer shot and killed Eugene, who bit into Poppo's face in broad daylight alongside a busy highway. Police have not released a motive for the attack on Poppo, who had been homeless for decades.

Poppo has undergone several surgeries and remains hospitalized.
