EDEN PRAIRIE (AP) — Eden Prairie police say the ex-boyfriend of a missing woman recently bought a gun legally, and an unspent bullet found by searchers is consistent with that gun.

But Police Chief Rob Reynolds says there is no forensic evidence that the bullet belonged to the man.

Police are trying to figure out where to search for 24-year-old Mandy Matula. Police say Matula's ex-boyfriend, David Roe, did a lot of traveling after she disappeared and before he committed suicide in the Eden Prairie Police Department parking lot, including making a trip to St. Cloud.

Matula was last seen late Wednesday. Roe agreed to talk to a police detective, but shot himself after pulling into the police parking lot Thursday and died the next day.

On Saturday, searchers found the unspent bullet near Miller Park.

Roe was a student at St. Cloud State University.
