MILWAUKIE -- A Southeast Portland man is facing several criminal charges stemming from what police are calling a "one-person crime spree" last month in Milwaukie.

Mark David Siebenmorgen, 46, is being held in the Clackamas County Jail, with bail set at $75,000. He was arraigned Wednesday in Clackamas County Circuit Court on charges of assault, menacing, harassment and criminal mischief.

Officer Ulli Neitch, Milwaukie police spokeswoman, said a man shoved another man to the ground without warning at the downtown Milwaukie bus mall around 9:35 p.m. Oct. 21.

Twenty minutes later, a man was reported flailing his arms and flexing his muscles as he jumped on the hood of a car parked near St. John the Baptist Catholic Church, Southeast 25th Avenue and Washington Street -- while a driver was behind the wheel. The man kicked and shattered the windshield before running away.

At 10:26 p.m., a man burst from the bushes and confronted a woman behind Milwaukie Market Place, 108 S.E. Oak St. As the woman walked away, the man threw rocks at her, striking her in the neck.

Police used a tracking dog but were unable to find the suspect.

The following day, employees of the Safeway store, Southeast 42nd Avenue and King Road, called police to report unsettling comments made by a customer.

Police then identified Siebenmorgen as the suspect and arrested him at his Southeast Portland apartment.
