Murder on the Cape
Christa Worthington was found murdered in her Truro, Massachusetts home. The list of suspects included two former lovers, but when DNA evidence of sexual relations didn't match either suspect, the D.A. widened the circle and asked for DNA from every man in Truro. Three and a half years after the murder, a surprising match was found.
In January 2002, Christa Worthington, a former fashion writer, was found murdered in her Truro, Massachusetts home. The expanding list of potential suspects included her former boyfriend, Tim Arnold, who had discovered her body; and ex-lover Tony Jackett, a married father of five children, whose affair with Worthington produced a daughter named Ava. DNA evidence was found on Worthington's body indicating sexual relations, but when the crime lab produced results a year after her murder, they did not match any of the potential suspects. With no match, District Attorney Michael O'Keefe widened the circle of his investigation and asked for DNA from every single man in Truro. Three and a half years after the murder, a match was found. Christopher A. McCowen, Worthington's garbage man, was arrested for her murder.
