Authorities have made an arrest in the stabbing death of a longtime Brother Rice High School teacher, Orland Park police said Friday.
The suspect was an acquaintance of the victim and was arrested in the early morning hours Friday, according to a police news release.
Law enforcement sources said the suspect is an Indiana prostitute solicited by the victim through an online classified service. Police are trying to determine if the killing was random or if the suspect went to the home specifically to kill the victim, a law enforcement source said.
Al Filan, 61, was found dead on the kitchen floor of his Orland Park home Tuesday when police went to his house after Filan didn’t report for work that day. The Cook County medical examiner’s office said Wednesday the cause of Filan’s death was multiple stab and incise wounds.
Orland Park police provided no other details about the arrest, and police did not immediately respond to requests for comment.
A spokesperson from the Cook County state's attorney's office said Friday night that charges had not yet been filed in the case.
Filan taught at Chicago's Brother Rice High School for nearly 40 years and coached soccer at Tinley Park's Victor Andrew High School from 1988 to 2010, the schools confirmed.
Filan, a 1974 graduate of Calumet College of St. Joseph's in Whiting, Ind., is part of a prominent Cook County family. His brother, Bill, is a Chicago lobbyist, and his sister, Denise, is a Cook County judge.
Police tape remained strung across Filan's front yard this afternoon, though police no longer had squad cars on patrol in front of the house, as they had Tuesday and Wednesday morning.
The investigation is continuing in conjunction with the South Suburban Major Crimes Task Force, police said.
