MARINETTE, Wis. — Seeking the public’s help, Marinette County authorities have released surveillance video and a still photo from the armed robbery Monday at the Stephenson National Bank & Trust in Pembine, Wis.

The video can be viewed on the Marinette County Sheriff’s Office’s Facebook page.

The robbery is under investigation with the assistance of the FBI, Wisconsin Department of Justice and Michigan law enforcement who are investigating a similar incident in Escanaba on June 5, according to the Marinette County Sheriff’s Office Facebook page.

The man, wearing a full face mask, robbed the bank about 1:18 p.m. Monday after showing a handgun, then fled in a vehicle described as a dark-colored, mid- to late-model GMC four-door mid-sized SUV, possibly an Acadia, with silver five-spoke wheel rims, Marinette County Sheriff Jerry Sauve said in a news release.

The white male was described as about 6 feet, 2 inches to 6-foot-5 in height, wearing light blue jeans, brown or tan shoes, a dark sweatshirt or jacket and gloves, along with the face mask.

The man is believed to be armed and dangerous, Sauve said in the statement.

According to an Escanaba Public Safety news release, a male dressed in black with a mask and carrying a handgun tried to enter the United Federal Credit Union about 5:53 p.m. Friday, but the building already had closed for the day and was secured, although an employee was still inside.

A surveillance camera showed the vehicle used was an older-model GMC Acadia, dark blue or black in color, with a sun roof.

Anyone with information about Monday’s robbery in Pembine is asked to contact Marinette County Dispatch at 715-732-7627.
