Sheriff's detectives need help solving a double homicide on a county island in Mesa nine months ago.
Maricopa County sheriff's deputies said they discovered Philip Marquis and Leila Ziegler brutally murdered inside a trailer on Nov. 5, 2012.
"They sustained multiple violent injuries to their entire bodies," said Maricopa County Sheriff's Office Detective John Little.
Since that time, Little has followed hundreds of leads to solve the murder mystery. All of them are hitting a dead end.
"We don't have a suspect in custody and we're beginning to run out of directions to go in," Little said.
Marquis was a retired postal worker and widower who had a tendency of helping young women who had no place to live.
It's believed Ziegler was one of those women. She was a mother of three. Her youngest child was a newborn.
It's a case that Little says bothers him.
"I can't look at their families and tell them this is the person that we have evidence to know did this and we're going to bring them to trial and let a jury decide whether they're guilty or not," he said.
Detectives collected a lot of physical evidence at the scene. Much of it has been submitted for DNA testing in hopes of getting a hit on someone already in the system. But so far the backlog at the DPS lab has left investigators empty handed.
"In this particular case we have a rush on the DNA and I'm currently going on seven months," Little said.
While Little continues to wait, he said he hopes someone comes forward with the tip he needs to identify a suspect.
Silent Witness is offering a reward of up to $1,000 for information that leads to an arrest and conviction in the case.
