Polk County authorities are saying little about the cause of last night’s four-hour standoff with a resident in a trailer park northwest of Des Moines. 52-year-old Dennis Miller of Grimes holed up in his trailer and fired four shots at officers. He told a friend he wanted to “commit suicide by cop” by forcing police to kill him. Residents of the trailer park were evacuated. Officers didn’t return fire. Miller faces charges of terrorism.
