What would it take to catch Bellingham's peeper?

In late October, he stepped out from behind a tree in Laurel Park, and masturbated while a woman walked by.

A week prior, he stood in a puffy jacket, and again masturbated on the back porch of a house on North Garden Street.

And just three days before that, he knocked on the window of a house to get the attention of a sleeping woman inside. He wore a tiger mask to conceal his identity, but wanted to make sure she saw him fondling himself.

These incidents are just three of the 20 or more cases of lewd conduct happening around Western Washington University that Bellingham Police say are connected to one white man in his 20s. Sgt. Claudia Murphy said the cases began in early August and have not stopped.

Murphy supervises the Family Crimes Unit at Bellingham Police.

“I’m not a psychologist, but I’ve been doing this for 25 years. People like this don’t just stop on their own. There are cases where behavior like this has escalated,” Murphy said. “I think like a lot of things, he’ll go until he’s caught.”
