Salt Lake City police were trying to determine whether a string of pharmacy robberies and attempted robberies on Monday were related.

The first incident was just after 9:30 a.m. at Smith's Food King, 402 E. 6th Ave. A man wearing a black hooded sweatshirt, gloves and black sweat pants gave the pharmacist a note threatening that someone would get hurt if he didn't get Lortab, said Salt Lake City police detective Jeff Bedard. The man, who had a beard with about four or five days' growth and brown hair, left after receiving an undisclosed amount of the painkiller.

Just before 8 p.m., the pharmacy at Albertsons, 2040 S. 2300 East, was robbed by a man who handed the pharmacist a note stating he had a knife and that he wanted Oxycontin, Bedard said. The man put the note on the counter but then left after an employee recognized him as the same man who robbed the store a few weeks ago, Bedard said.

That suspect was wearing a tan hat, tan jacket, tan vest and a long-sleeved plaid shirt. Employees said he also had bad acne on his face.

About 25 minutes after that robbery attempt, a man walked into another Albertsons at 370 E. 200 South. The man handed the pharmacist a note demanding Oxycontin and saying he had a knife in his hand, Bedard said. This time, the pharmacist could see the knife, he said. Rather than give him drugs, however, the pharmacist walked away and the man fled the store.

The man in the third incident was described as wearing a gray safari-type hat, gray clothing, a black vest and a dark blue sweater.
