BURNSVILLE (AP) - Family and friends of a missing University of Minnesota student continue to look for the 20-year-old woman while police are warning that public participation in a search could compromise a possible crime scene.

The family of Anarae Schunk says the greatest potential contamination of any possible evidence is time. Schunk's family is asking for "all hands on deck to bring her home safely."

Schunk has been missing since early Sunday after she was seen with her ex-boyfriend, Anthony Lee Nelson, at Nina's Grill in Burnsville. Nelson is charged with fatally shooting Palagor Obang Jobi in the parking lot after they'd gotten in a fight because Nelson was angry that he was talking to his girlfriend. That woman, Ashley Conrade, is charged with harboring Nelson at her townhouse until his arrest Tuesday.
