A suspect arrested in the Nov. 19, 2015, robbery of Ankeny’s Mini Mart No. 4 has pleaded guilty as part of a plea agreement.

Bradley Matthew Clark, 21, of Austin, pleaded guilty to a felony charge of aggravated robbery and possession of a dangerous weapon in Mower County District Court on Monday.

According to court records, he admitted to police to using the money to buy drugs.

Officers responded to Ankeny’s Mini Mart No. 4, 902 12th St. SW, around 8:45 a.m. Nov. 19, 2015, to a report of an armed robbery.

The suspect, later identified as Clark, was said to have left on foot walking toward the fairgrounds, according to the report.

Officers arrived and searched the area, finding a homeowner with a surveillance video in the 1800 block of Eighth Avenue Southwest. The video showed Clark riding a bike past the residence.

An Ankeny’s employee reported she was at the south end of the counter when Clark came into the store and demanded money wielding a fixed-blade hunting knife. He was wearing a black hooded sweatshirt with white swirls, a red ski mask that covered his nose and mouth, and gloves. The employee gave him about $175 from the register in various denominations.

Clark reportedly told the employee to get on the floor and then he went to the door. When the employee knew he was gone, she pushed the alarm button, locked the door and called 911.

Officers confirmed the employee’s story through the store’s video surveillance, which showed the suspect running across the parking lot toward some pine trees on the west side of the parking lot. Officers spoke with neighbors and identified Clark as a possible suspect, according to the report. Clark had been residing on the 700 block of 18th Street Southwest, a few blocks from the robbery.

On Nov. 20, Officers spoke with someone Clark was living with who said he moved in with her about a week prior. She confirmed he had a bike and hoodie similar to the ones the suspect had. Officers searched the home with consent and found Clark in the basement, according to the report.

The report stated Clark did not act surprised by the news he was a suspect in the robbery, and he admitted to being a heroin addict when officers found “a significant amount of heroin paraphernalia” in the basement. Officers found the bicycle and later found the clothing and knife used in the robbery, with the cooperation of Clark.

Officers arrested Clark and interviewed him at the Mower County Jail, but the report stated he initially did not speak much or respond to questions but asked several of his own.

However, in a subsequent interview, Clark reportedly admitted to the robbery and said he “turned around six times” before he actually went into the store. He said he used the money to buy drugs and that nobody else was involved.

Sentencing is scheduled for Feb. 2, 2017.
