SUMNER, Iowa (AP) -

A second suspect has pleaded not guilty to 35 counts stemming from a northeast Iowa bank robbery and shot-filled police chase.

William Clayton, 19, made his plea Monday in Bremer County. The charges include attempted murder, terrorism, assault and robbery.

The other suspect, Jeremiah Mumford, 24, has already pleaded not guilty.

Authorities say the two robbed the Maynard Savings Bank in Maynard on Oct. 30 and then shot Sumner Police Chief Dennis Cain and Iowa State Trooper Mark Domino during the chase afterward. Mumford and Clayton eventually were cornered and then arrested in a rock quarry outside Frederika, about 30 miles from Maynard.
