Michael DiNardo, the son of former LSU football coach Gerry DiNardo, was arrested this week in Baton Rouge under felony drug and firearm charges.

Michael DiNardo, a 21-year-old student at LSU, was booked Wednesday by the East Baton Rouge Parish Sheriff’s Office for the intent to distribute marijuana and possessing a firearm with drugs. He was also charged with possession of drug paraphernalia.

Bail had not been set as of Wednesday afternoon.

Gerry DiNardo did not return a message for comment.

DiNardo coached at LSU from 1995-99, a five-season tenure that ended with his firing 10 games into his last year.

A package, smelling of marijuana, at the Bennington Avenue post office sparked an investigation and led to the arrest of Michael DiNardo, of 400 Lake Beau Pre Blvd.

Postal workers called the sheriff’s department about the package, and a drug-sniffing dog identified the package as containing narcotics, according to an affidavit of probable cause sent to The Advocate from the EBR Sheriff’s Office.

A post office employee identified Michael DiNardo through photograph as the person who dropped off the package. The package was also addressed from DiNardo.

Questioned about the package, DiNardo told authorities he dropped it off and that it contained “a quarter pound of marijuana,” the affidavit said. Authorities then executed a search warrant at DiNardo’s address. They uncovered “several plastic bags of marijuana, a scale and two firearms,” the affidavit said. One of the firearms was an AK-47.

Possession with intent to distribute is punishable by 4-10 years in prison and a fine up to $5,000. Possession of a firearm with drugs is punishable by six months in prison and a fine up to $500.

At LSU, Gerry DiNardo went 34-24-1, with 26 of those wins coming in his first three seasons. The Tigers plummeted to back-to-back losing years in 1998 and ’99, and the school replaced him with Nick Saban.

DiNardo coached at Vanderbilt for four seasons before being hired at LSU. He coached Indiana for three seasons after his stint in Baton Rouge, leading the Hoosiers to just eight wins before being fired in 2004.
