PALOS PARK, Ill. — Three people from Indiana and an Illinois man have been charged in connection with a suburban Chicago home invasion that left an accomplice dead.

Prosecutors say it was a sexual tryst and robbery plot gone wrong.

Prosecutors say the homeowner arranged to have sex with one of the women in his home. She allegedly plotted to let her friends into the south suburban house Tuesday night to rob the man at knife point.

The Palos Park homeowner shot and killed 19-year-old Anthony Dalton of Cedar Lake on Tuesday. An accomplice, 23-year-old Tyler Gulli of Midlothian, Illinois, was wounded.

Cook County Sheriff's Department officials say Gulli, 20-year-old Sarah Risner of Crown Point, sisters, 19-year-old Brandy Marshall of Dyer and 20-year-old Paige Marshall of Hammond, were charged Thursday with first-degree murder.

Police say the homeowner, who wasn't identified, had a valid concealed carry license and does not face charges.

It wasn't immediately known if those charged have obtained legal representation.
