MIDDLETOWN, Conn. (AP) _ Connecticut state police have arrested a Windsor Locks police officer on manslaughter and motor vehicle charges after his car struck and killed a teenage bicyclist last month.
Michael Koistinen was released Thursday on a $50,000 cash bond. He will appear in Superior Court in Hartford on Tuesday on charges that also include an attempt tamper with physical evidence.
His attorney has said Koistinen had been drinking but was not drunk at the time of the Oct. 30 accident that killed 15-year-old Henry Dang.
Koistinen was off-duty when the crash occurred. He is on leave pending a state police probe into why colleagues failed to ask him to submit to a blood alcohol test.
Koistinen’s father, Windsor Locks Sgt. Robert Koistinen, was among the responding officers but did not participate in the investigation.
