A man has been charged in connection with a double shooting aboard a Pink Line train in the Loop that left one man dead and another injured just before Christmas.
Pedro Villarreal, 34, is scheduled to appear in court Monday for a detention hearing on charges that include murder, attempted murder, and unlawful possession of a weapon, authorities said.
The shooting happened around 1:22 a.m. on December 23 aboard a Pink Line train near the Washington-Wells station. Last month, CPD said a 23-year-old man and a 44-year-old man were riding the train when they became involved in a verbal altercation with an unknown man who was armed with a knife.

The dispute escalated into a physical fight, at which point one of the victims produced a firearm, police said in an initial media statement released last month. During the struggle, the offender gained control of the gun and fired it, police said in a statement after the shooting.
The 23-year-old was shot in the wrist and ran from the train. He was taken to Northwestern Memorial Hospital, where he was listed in fair condition.
Officers later found 44-year-old Raymond J. Harrison Jr. still on the train, unresponsive with a gunshot wound to the abdomen. Police administered CPR and other lifesaving measures before Harrison was transported to Northwestern, where he was pronounced dead.
Investigators recovered a shell casing from the train near Harrison’s body. At least one of the victims appeared to be homeless and was traveling with a bag of clothing.
