An investigation into the case uncovered serious criminal activity associated with Chicago horse stable owners, including Silas Jayne and Richard Bailey.
[2] After a routine medical check-up at the Mayo Clinic in Rochester, Minnesota, Brach left for a flight to return to her mansion in Glenview, Illinois,[3] a suburb north of Chicago, on February 17, 1977.
Matlick further asserted that Brach spent four days at home, that she made no phone calls, and that he dropped her off at O'Hare for a flight to Florida.
He repeatedly proclaimed his innocence and angrily denied to reporters that he knew what happened to Brach, but a former federal agent who worked on the case claimed after Matlick's death that he was indeed responsible for her disappearance.
[4][5] Brach's brother was of the opinion that Matlick had murdered his sister without any involvement from Richard Bailey or horse racing racketeers.
[6][7][8][9] On February 14, 2011, three days before the 34th anniversary of Brach's disappearance, Matlick died in a Pennsylvania nursing home at the age of 79.
[15] In 2022, Bailey released a book with Dorrance Publishing Company titled Golden Tongue: The Innocent Man that Killed Her?
