COOK COUNTY CRIMINAL COURTHOUSE — In his dying words, a man gunned down in a drive-by told people at the scene that "Bo" shot him, prosecutors said.
Tywan Mason, 23, also known as "Bo," has been charged in the double murder of Lamont Matticx and William Herron-Junius, who were slain in a drive-by in the Back of the Yards almost a year ago.
He was implicated by his co-defendant, Anthony Johnson, and arrested Wednesday, Cook County Assistant States Attorney Stephanie Buck said.
Lamont Matticx and William Herron-Junius, both 20, were sitting near the porch of a home in the 5300 block of South Hoyne Street at about 5 p.m. on May 10, 2012, when a white Chevrolet Tahoe rolled up from the west.
From the passenger seat, Mason allegedly leaned across the driver and opened fire before the SUV sped away, Buck said.
Herron-Junius was shot in the head and died on the scene. Matticx was taken to Mount Sinai Hospital in critical condition with a gunshot wound to the chest and pronounced dead about an hour later.
But before he died, Matticx told witness at the scene that "Bo shot him," Buck said.
Buck said police found the Tahoe and charged Anthony Johnson days later.
Johnson allegedly fingered Mason, who was also identified in a line-up by a witness.
A Cook County Judge ordered him held on $3 million bond Friday.
