Police arrested a man Friday afternoon after finding him unconscious with his finger on the trigger of an AK-47 rifle in his car near the Parade Ground.
LSUPD arrived at the scene after witnesses reported seeing a man, later identified as Trevis Williams, 18, slumped over in his seat with a gun in his lap parked in the roadway.
Williams did not wake up when police approached the vehicle on the corner of Highland Road and Dalrymple Drive or when they broke the window to gain entry around 3 p.m.
After handcuffing Williams, police found 28 rounds in the magazine of the 7.62 caliber rifle, but no rounds in the chamber and discovered several forms of illicit substances in the vehicle, according to the arrest report.
Police found 41 grams of marijuana in 27 pre-packaged plastic bags, 55 Xanax pills split between nine packages and 30 ecstasy tablets, according to the report.
Williams was booked into East Baton Rouge Parish Prison on charges of illegal carrying of a firearm with narcotics, felon in possession of a firearm, three counts of possession with intent to distribute and parking where prohibited.
Carrying a firearm while in possession or during the sale or distribution of a controlled substance is against the law under R.S. 14.94. It also is illegal under Louisiana law to be in possession of a dangerous weapon on school property.
The regulations and penalties for possession with intent to distribute marijuana and ecstasy, classified as Schedule I drugs, are higher than those for possession with intent to distribute Xanax, a Schedule IV drug.
Controlled substances are split into these categories under the Drug Abuse Prevention and Control Act based on the potential for abuse and the potential for psychological and physical dependency.
Williams, who is not an LSU student, was convicted in June 2014 of attempted felony theft, according to the police report.
