Four Tigard police officers have been placed on administrative leave after a chase with a suspected robber and his wife ended with gunfire outside a Tualatin pharmacy Tuesday, police spokesman Jim Wolf said.

One of the officers placed on leave, 14-year department veteran Andrew Pastore, was directly involved in a shooting that left accused robber Josh Luther with injuries that weren't life threatening, Wolf said. The other three were placed on leave because Josh Luther allegedly shot at them during the chase, which Wolf called "extremely intense."

It is standard procedure for the Tigard police department to place officers who are involved in a shooting on administrative leave, Wolf said.

The chase began Tuesday morning after Josh Luther is suspected of robbing a Southwest Portland hotel and fleeing off in a white minivan driven by his wife, Michelle Luther, police said. Police found the minivan at a Tigard gas station and pursued it through several cities.

Police said Josh Luther fired several bullets at officers as his wife drove. Ten minutes after the chase began, the van stopped in front of a Walgreens on Lower Boones Ferry Road in Tualatin. Officers chased Josh Luther, and one of them shot him as he tried to escape, Wolf said.

Josh Luther is being treated at OHSU Hospital for injuries that don't threaten his life, police said. Michelle Luther was arrested and charged with attempted aggravated murder.

Three children were in the van during the chase. Police have not said how the Luthers were connected to them.
