WOODSTOCK – Police have arrested a Woodstock man they say stabbed his stepson to death Saturday afternoon.
Victor Lopez, 46, 1780 Sheila St., Woodstock, was arrested late Monday afternoon and charged with first degree murder. Police picked him up from a hospital – where he'd been receiving treatment for facial injuries he suffered during the incident – and took him from there to the jail, Woodstock Police Chief Robert Lowen said.
Lopez is charged in the death of Mark A. Medina, 34, 1978 Sheila St., Woodstock, who died of multiple stab wounds, according to the McHenry County Coroner’s office.
Lowen said the incident was "some kind of domestic dispute going on with the families."
Police were dispatched about 4:40 p.m. Saturday to Medina's residence for a report of a nonresponsive man, according to a news release from the Woodstock Police Department.
When they arrived, they found Medina dead, with stab wounds to his chest. He had been dead for "a period of time prior to arrival," the release said.
Preliminary findings from an autopsy Sunday revealed Medina died of the stab wounds. Toxicology results are pending.
Police quickly identified Lopez as a suspect. They located him at a family member's residence and took him into custody Saturday night, the release said.
Lopez was taken to a hospital for treatment before being formally charged Monday afternoon.
Police believe Medina and Lopez were the only two people involved in the incident, Lowen said.
Residents along Sheila Street described Sunday a heavy police presence around the home where Medina was found near the intersection of Central Parkway Road and Julie Street. But neighbors said that the neighborhood seemed normal before police arrived, with no one acting suspicious.
Woodstock police had assistance during the investigation from the Major Investigation Assistance Team, a specialized major crimes unit made of investigators from numerous McHenry County police departments and the Illinois State Police.
When Medina was 16 years old, a jury acquitted him on attempted first-degree murder charges, and instead convicted him of aggravated battery with a firearm and aggravated discharge of a fire arm. For those crimes, a McHenry County judge sentenced him to 15 years in prison.
Medina was affiliated with a street gang, court records show. But he insisted after the 1996 incident that it wasn't gang related.
According to court records, after a confrontation, Medina shot the victim once in the chest and the victim survived.
Lopez also has a previous record of violence. He was charged with battery with intent to cause bodily harm in 2002.
He was charged with domestic battery for a 2009 incident, but that charge was later reduced to assault.
For each incident, Lopez was ordered to complete a year of court supervision.
