"I don't know if Peter ever wanted to be a hero, but he wanted to be the best damn police officer he could and we all know he fulfilled that," his mother, Patty, said in a statement.
At Western States in Butler, Milwaukee Officer Peter Jerving was known as "Pete." His two "mother hen" co-workers would regularly check in with him after he became a police officer. When they heard of a shooting Tuesday, they sent a text and never heard back.
