BOISE, Idaho (AP) — No charges will be filed against Boise police following a 22-month federal investigation into allegations officers stole items from searched homes. U.S. Attorney Wendy Olson in Idaho in a letter to Boise Police Chief Mike Masterson says there isn't enough evidence to prove officers violated Fourth Amendment rights of individuals. The Idaho Statesman in a story on Friday  reports it obtained the Dec. 18 letter through a public records request. The investigation included a grand jury probe that ended without indictments. Olson declined to provide details of the investigation, including the names of any officers who might have been investigated.
