University of Mississippi student Jimmie "Jay" Lee has been missing for a week, and police and his father are asking for anyone with information to come forward.

"No tip is too small," the Oxford Police Department said in a statement Thursday.

The 20-year-old was last seen Friday morning leaving the Campus Walk Apartments at Ole Miss around 6 a.m., according to the Oxford Police Department, which said Lee was last seen wearing a "silver robe or housecoat," gold sleeping cap and gray slippers.

Authorities say a tow company removed Lee’s car from an apartment complex near the Molly Barr Trails in Oxford, Mississippi, later that day, off campus about 2.5 miles away. They recovered it Monday at the tow yard and brought it to the state crime lab for processing, police said.

Police said they believe Lee may have been visiting someone at the apartment complex.

"I am asking that if anyone knows anything, or sees anything, say something," Lee’s father said in a 2-minute video shared by Oxford police. "Call, contact law enforcement, just tell them what you know. This is my plea that you help find my child."

He described Lee as a hard worker who wanted to help others.

"My son was currently working on an effort to provide infant formula to children who did not have it available," he said in a 2-minute clip.
