ABC15 takes you back to one of the most horrific murder scenes in Maricopa County. Almost 10 years later, whoever killed 70-year-old Philip Marquis and 30-year-old Leila Ziegler, has never been found.
On April 29, 2014, officers were called to a home in Paradise Valley, where a 68-year-old businessman named Michael Gilman was found dead. 8 years after Gilman's death, police are still looking for the person responsible for his death.
