Lab tests detected only marijuana in the system of a Florida man fatally shot while chewing another man's face, the medical examiner said Wednesday, ruling out other street drugs -- including the components typically found in the stimulants known as bath salts.

There has been much speculation about what drugs, if any, would lead to the behavior that Rudy Eugene exhibited before and during the attack that left the other man disfigured.

The Miami-Dade County Medical Examiner said in a news release that the toxicology detected marijuana, but it didn't find other street drugs, alcohol or prescription drugs. Eugene also tested negative for adulterants commonly mixed with street drugs. It's not clear what led to the May 26 attack on Ronald Poppo, 65, who remains hospitalized.
