They're devoting extra resources and personnel to try and find who killed Allison Feldman in her Scottsdale home.
They say they are still weeks away from processing all of the evidence they collected, FOX 10 spoke with the commander in charge of the investigation.
Allison Feldman was just starting a very successful life, a good job, a boyfriend, a new home in a safe Scottsdale neighborhood, but her life ended with a murder that is still unsolved a month later.
"I think most of us have Aunts, Sisters, and Daughters that age, and to think about somebody coming in and taking her life is disturbing to me, so we're going to do anything we can to catch the suspect," said Commander Tom Henny.
Scottsdale Police Department Commander Tom Henny says Allison's murder is the top case at the department. Over three dozen personnel are working on it and DNA evidence taken from the home will take another two weeks to process.
The big question; was it a stranger, or someone she knew?
"It could be someone who lives in the neighborhood, it could be a random act of violence, we simply don't know right now," he said.
Her boyfriend who discovered her body has been questioned multiple times, and he's given a DNA sample, but he has not been named a suspect, neither has he been completely ruled out, some invasions and murders are very rare.
"We have nothing to make us believe that she was targeted in this case, but we also don't have anything that tells us that she wasn't," said Henny.
The bottom line here is more than a month after the murder there is no suspect, and nobody is under surveillance.
But that could change as all the DNA evidence is processed.
FOX 10 will stay on this case and provide updates as they develop.
