A mental evaluation has been ordered for an armed man who police found watching the bar where an Indiana University student was last seen.

The 56-year-old man told police he had been in the parking garage watching the Bloomington bar where Lauren Spierer partied with friends before she disappeared in June 2011. Police said Wednesday that the man had two loaded semi-automatic handguns in his pockets and a loaded shotgun in the trunk of his car when he was discovered Saturday. 

Officers found another 48 weapons when they searched the man's Indianapolis home Sunday.

Police say the man made bizarre comments about Spierer's disappearance and claimed he met her once at a shooting range.

Police Captain Joe Qualters said the man wasn't believed to be involved in Spierer's disappearance.
