An Arlington Heights teenager is being held without bond Monday on allegations that he worked with three others to beat, rob and kill his father.
Mathew Nellessen, 19, of 1000 block of North Wilshire Lane, faces first-degree murder and robbery charges along with three Chicago men, Arlington Heights police said.
The other suspects, from Chicago, are Armon Braden, 20; Azari Braden, 19; and Marlon Green, 20. They're all being held on bond, the highest being $3 million.
George Nellessen's lifeless body was discovered Thursday duct-taped to a chair, gagged and with a bag over his head in the home he shared with his only son. An autopsy determined the elder Nellessen suffered neck and head trauma and died of several sharp-force injuries.
Prosecutors believe Mathew Nellessen killed his father by stabbing him to death after Green hit the man five times in the back of the head with a baseball bat while he was duct taped to a chair.
All four defendants were trying to steal money from the elder Nellessen and even forced him to sign a check for $100,000 from his retirement account; prosecutors said during Monday's bond hearing.
Betty Zak, the mother of George Nellessen, told local papers her son didn't deserve to die at the hands of his own son.
Zak said George Nellessen hoped the teen, who had several run-ins with the law, would get his life together.
