A man who was held at a Minnesota treatment facility for convicted sex offenders was captured by police after making his escape by attaching his GPS monitoring device to a dummy.

Based on a criminal complaint accessed by local Fox station KMSP, Steven Loren Edwards, aged 53, was declared missing on Saturday. The complaint details that Edwards’ roommate informed the treatment center staff around 7 p.m. that Edwards—who was first admitted to the St. Peter Treatment Center under the Minnesota Sex Offender Treatment Program in October 2011—had remained in bed all day, without any apparent movement for “quite some time.”

When the staff pulled the bed’s blanket back, they found a dummy wearing the GPS ankle bracelet assigned to Edwards.

According to court documents, staff observed Edwards allegedly leaving the facility on surveillance camera footage shortly before 7 p.m. on Friday.

As police began to figure out Edwards’ whereabouts, court documents stated that they found out the alleged escapee had placed a phone call to his son following his exit from the facility. The documents stated that he used a phone that was associated with an unnamed man who was using a nearby laundromat on Friday night.

The man reportedly told police that he witnessed Edwards enter the laundromat and told him that he had been kicked out of the house and needed a ride to Albert Lea, Minnesota. The man told police that he agreed to drive Edwards to where he needed to go, and the pair reportedly took a detour to a casino in Iowa.
