A second suspect in the shooting of a postal worker last month was arrested early Monday, police said.
Keyon Taylor, 21, of Boston, was arrested at 1:18 a.m. on Blue Hill Avenue. He faces charges of kidnapping a federal employee, assault on a federal employee, and conspiracy, officials said.
Another suspect, Maurice Williams Miner-Gittens, 23, was arrested Wednesday and faces the same charges.
Both suspects are being detained, pending indictment by a grand jury in the next 30 days, according to the US attorney’s office.
If convicted, each man faces up to life in prison on the kidnapping charge, up to 25 years on the assault charge, and five years on the conspiracy charge, according to the US attorney’s office.
The robbery occurred on Dec. 20 in Dorchester near the MBTA Red Line’s Ashmont station, when Miner-Gittens and Taylor allegedly jumped into the postal worker’s truck while he was delivering holiday packages and put a gun to his head.
An ensuing struggle led to the postal worker getting shot in the wrist and beaten with the pistol, then ordered by the two suspects to remove his uniform and lie down, authorities said.
As Taylor drove the postal truck away, the letter carrier, who was bleeding, jumped from the back door and ran.
Authorities said Taylor drove the truck a short distance away before abandoning it and fleeing on foot, leaving behind a trail of boot prints in the snow that led through several back yards and to a trash bin with Taylor’s blood on the lid. The postal worker’s uniform, cellphone, and keys were in the bin.
Authorities said they found the postal worker’s blood inside the U-Haul van that Miner-Gittens had rented and used during the attempted robbery.
The US Postal Service offered a reward of up to $50,000 during the investigation for information leading to Taylor’s arrest.Globe correspondent Jennifer Smith contributed to this report. Catalina Gaitan can be reached at catalina.gaitan@
