Feds report arrest of man they say really liked holding up a gas station in Readville, but who branched out to convenience stores

Tykei Hallman, 25, of Hyde Park, a 6'6" former high-school basketball player who now walks with a limp, is scheduled for arraignment in federal court today on a count of robbery involving use of a firearm for the robbery of a Quincy convenience store - but he is the suspect in 15 robberies and robbery attempts in the Boston area - three of them robberies at Mobile station on Neponset Valley Parkway in Hyde Park's Readville section and a failed robbery at Rogers Service down the street.

The US Attorney's office reports Hallman faces up to 20 years in prison on the robbery charge, with an additional 7 years possible for using a gun during the commission of the crime.

According to the charging document, between May 2019 and November 2019, approximately 15 convenience-type stores were robbed in the Greater Boston area by a masked and armed individual. During each robbery, the suspect who appeared to be a male, was dressed in dark hooded outer garments, a mask obscuring his face and gloves. The suspect entered the convenience stores brandishing what appeared to be a black and silver semi-automatic handgun and demanded the stores’ cash. Based on the similarity of the robberies, witness statements, and video surveillance obtained from the locations, law enforcement determined that the same individual was responsible for these robberies. Hallman was identified as the robbery subject through physical surveillance, GPS data from cell phones and motor vehicle records.

An affidavit by an FBI agent who tracked him lists several markets he allegedly robbed at gunpoint in Hyde Park and Roslindale, including the Fairmount Food Market, 674 Truman Parkway in Hyde Park on May 24, getting away with $300 to $400 after waving a gun at a cashier. He returned to the store on July 12, again with a gun and this time made off with $1,000. On Aug. 19, he robbed MVP Liquors, 4339 Washington St. in Roslindale, of an unknown amount of money. On Aug. 23, he took roughly $400 from the cash register at the Pit Stop, 695 Truman Parkway in Hyde Park.

He also robbed markets in Milton and Quincy - which helped bring about his capture, because Quincy Police had given one potential target store a tracking device to toss in with any money - according to the affidavit. Hallman allegedly robbed the Five Corner's Market on Nov. 5 and Hallman escaped with both cash and the tracker.

Although the tracker stopped moving on I-93 north in Dorchester - at the Savin Hill overpass, where he seemed to have discovered and tossed it - surveillance photos from stores and homes along the route, one of which included the car's license plate, led investigators to an Arlington woman, who was apparently going out with Hallman's brother. Investigators began to figure that out after they followed the woman one night from her Malden workplace to Garfield Avenue in Hyde Park, near the Milton line, where she picked up a man and drove with him to Legacy Place in Dedham for dinner at Sweetgreen.

Boston Police set up a pole camera - and began a stakeout - at the apartment complex and, over the next few days, spotted the man having numerous discussions with a tall man wearing red and black sneakers, just like the suspect in all the robberies.

believe, based on my review of video/photos of HALLMAN and my review of surveillance footage of the robberies discussed above, that HALLMAN committed these robberies. HALLMAN closely resembles the perpetrator who appears in the surveillance footage.

Investigators then got warrants to obtain cell-phone location data from phones Hallman used - and that placed at least his phone at the location of many of the robberies.

Innocent, etc.
