(CBS/WBBM) PALOS PARK, Ill. - Police in suburban Chicago have arrested 17-year-old high school student John Granat for allegedly beating his parents to death in their home.
The teen is charged with first-degree murder and is set to appear for a bond hearing at 9 a.m. Tuesday.
His father, also named John Granat, 44, and mother, Maria Granat, 42, were found dead Sunday in their home in Palos Park, about 25 miles southwest of Chicago.
According to CBS station WBBM, autopsies on Monday found the elder Granat died from multiple blunt force injuries from an assault, while Maria Granat died from multiple blunt and sharp-force injuries. Both deaths were ruled homicides.
Cook County Sheriff's police said the younger John Granat called 911 from the family's home and told police his parents were dead. After questioning the boy about his activities before calling 911, detectives concluded that the boy had brutally beaten his parents to death in their bedroom.
WBBM reports that charges were approved late Monday night.
Neighbors told the station that the family had lived in their Palos Park home for a while. The father was a local contractor and owned a family home improvement and landscaping business in the area.
