Glenwood robbery suspect tied to Clifton case

A Denver man is in jail on suspicion of robbing a Glenwood Springs bank and in connection with two bank robberies in Colorado Springs. He is a person of interest in a Clifton bank robbery, as well.

An arrest warrant was issued for Mark Douglas Osterloo, 45, Monday in connection with the April 27 robbery of US Bank at 802 Grand Ave., Glenwood Springs police said in a news release. He is charged through the warrant with aggravated robbery, theft and menacing, all felonies.

He is being held in the Denver County Jail on $20,000 bond pertaining to the warrant and similar charges in two bank robberies in Colorado Springs on June 4 and 14, Glenwood police say.

Meanwhile, Mesa County sheriff’s spokeswoman Heather Benjamin said investigators also are looking at information possibly linking Osterloo to the April robbery of the Alpine Bank in Clifton. That robbery occurred a day before the Glenwood robbery.

“He is absolutely being investigated,” Benjamin said.

Benjamin said patterns displayed by the robber in each instance and similarities in appearance are among the things being examined.

The robber didn’t use force or openly display a weapon in any of the incidents, authorities say. However, he indicated in each case that he had a weapon, and at least some of the cases involved handing tellers a note.

Larry Herbert, a Colorado Springs police spokesman, said Osterloo was arrested after the second robbery there, based on a license plate provided by a witness. The descriptions of the robber and his clothing were similar in both Colorado Springs robberies.

Glenwood police said sharing of information between agencies on statewide networks designed to help investigators in different jurisdictions connect criminal patterns was crucial to obtaining the warrant.

“The professionalism and calm response of our local bank employees was key to this successful outcome,” Glenwood police added in the release.

Glenwood Springs police Lt. Bill Kimminau said a bank teller in the Glenwood case positively identified Osterloo in a photo lineup.

This is the second arrest related to a Roaring Fork Valley bank robbery in less than a week. Jeremy Harmon, 38, of Glenwood Springs was arrested for robbery Friday of the same mid-valley Vectra Bank that was robbed in March. Basalt police Sgt. Stu Curry said authorities still are looking into whether Harmon may have been responsible for the March incident as well.
