DES MOINES, Iowa (AP) — Police in Des Moines, Iowa, say two officers who were killed in ambush-style attacks were both shot while they were sitting in their patrol cars.

Des Moines Police Sgt. Paul Parizek said Wednesday that authorities are developing suspect information but there was nothing that authorities were ready to share with the public.

Parizek was emotional during a news conference. He says there is “clearly danger” right now for police officers in the area because the officers were gunned down while sitting in their cars doing nothing wrong. He says the department has doubled up its officers to better protect them.

The first officer, an Urbandale officer, was shot about 1:06 a.m. About 20 minutes later, a Des Moines officer was found shot about 2 miles away.
