CHICAGO (CBS) — A husband, wife, and son were found dead Monday night in their home in Oak Forest, and police said they were the victims of an apparent murder-suicide.
David Joost, 54, his wife, Margaret O’Leary-Joost, 55, and their son, Daniel Joost, 18, were found dead after police conducted a well-being check at their home in the 6600 block of Courtney Drive around 8 p.m. Monday.
Oak Forest Police Chief Gregory Anderson said a co-worker of Margaret Joost requested the well-being check after she did not show up for work on Monday, and did not call in sick. She also had missed work on Friday, but called in sick then, Anderson said.
When officers arrived at the Joost family home Monday night, they saw blood seeping from under the garage door.
“Officers forced entry into the home, and found a gruesome scene,” Anderson said.
Margaret Joost and Daniel Joost were found in their beds, and both appeared to have been strangled, Anderson said.
David Joost was found dead in the garage. He had left the car running in the garage, slit his wrists, and hung himself, but had collapsed to the ground by the time police arrived.
A preliminary investigation indicated the Joosts died Friday night or very early Saturday. He said it’s not uncommon, when a person hangs himself or herself, that the weight pulling on the rope or belt that was used will cause it to collapse.
