An Indiana man is accused of stealing about $69,000 worth of prescription drugs from Walgreens pharmacies in St. Paul and Edina.

Michael Iman White, 19, of Muncie, Ind., was charged Tuesday with two counts each of robbery and attempted robbery for a string of armed holdups that occurred in April and July, according to an indictment filed in U.S. District Court.

White, who is in custody, pleaded not guilty to the charges during an arraignment Tuesday afternoon before a federal judge in Minneapolis, court documents say.

On April 3, a man wearing a reflective vest and wielding a handgun held up a pair of St. Paul Walgreens stores, according to charges filed in August. In the first case, he fled the store at 1585 Randolph Ave. without taking anything. In the second, he made off with about $18,000 in prescription drugs from the store at 1110 Larpenteur Ave.

On July 16, the same man and two accomplices again attempted to rob the Walgreens at 1585 Randolph Ave. in St. Paul, but they fled when the security alarm sounded, the charges said. The following day, the trio stole about $51,000 in narcotics from a Walgreens in Edina. Related Articles St. Paul woman sentenced for manslaughter in man’s death; murder charge dismissed

Investigators used cellphone tower records to identify a single number that had been in the area of all four pharmacies when the robberies took place and found it belonged to White, according to the charges against him. They then used White’s driver’s license photo and Walgreens surveillance footage to identify him as the man involved in all four robberies, the charges said.

A pharmacist who was working at the Edina Walgreens when it was robbed also picked White out of a line-up as one of the robbers, the charges said.

White’s next court appearance is scheduled for Nov. 7.
