The parents of an LSU student who's been missing for almost two weeks held a news conference Friday asking for the public's help in find the missing 21-year-old.

Michael Nickelotte Jr. was reported missing after he was last seen Sept. 18 at East Campus Apartments and is believed to have left on his own, police have said.

Nickelotte's father, Michael Nickelotte Sr., wiped away tears as he spoke, asking the public to check surveillance video and report anything suspicious to LSU Police.

"Our whole purpose here is to keep the message alive that we want our son back," Michael Nickelotte Sr. said as he stood next to his wife, Paulla Nickelotte.

The couple stood in front of a banner with pictures of their son and his green mountain bike, which is also missing. Family and friends put out a dozen lawn signs on the levee with Michael's story and pictures.

The Nickelottes have enlisted the help of the Klaas KIDS Foundation, a Pensacola, Florida, based nonprofit that assists families in searching for missing children. Klaas Deputy Director Ray Mooney said his organization was asked to help earlier this week.

Nickelotte, who's from Mandeville, is described as being 6 feet, 1 inch tall, has blue eyes and a military-style haircut.

LSU spokesperson Ernie Ballard has said Nickelotte isn't involved in LSU's Greek Life system, and the case isn't related to the death of fraternity pledge Max Gruver.

Ballard said Friday that there haven't been any updates in the LSU Police Department's search or investigation.

"LSU police are working closely with the Nickelotte family and are talking with them daily about the search efforts," Ballard said. "In addition to LSU police specific responses, among the efforts include flyers sent out to law enforcement agencies, media outlets and emailed to all of the LSU campus through broadcast message."

Michael Nickelotte's picture and the phone number for the LSU Police Department have also gone up on digital billboards around Baton Rouge.

Ballard asked anyone with information on the case to contact police at (225) 578-3231.
