Salt Lake police say four recent robberies of gas stations or convenience stores are probably the work of one man or group of men.
Shortly before midnight Saturday, a man robbed the Rainbo Oil station at 874 E. 1300 South.The following night, the Circle K store at 701 E. 2700 South was robbed about 9:40 p.m. by a man who threatened to shoot the clerk. At 11:30 p.m., the Sinclair Gas station at 105 W. 600 South also was robbed, this time by two men, one of whom may have held a sawed-off shotgun under his shirt.
About 3:15 a.m. Monday, a man carrying what appeared to be a sawed-off shotgun under a shirt robbed the Circle K store at 505 S. Redwood Road.
"We definitely believe they are related," said Lt. Marty Vuyk.
Investigators are reviewing a tape shot by a security video camera during one of the robberies to try to identify the suspect.
