The mysterious murder of the 31-year-old woman found dead in her home has generated national headlines and several leads — but no arrests.
Family members told ABC15 they appreciate detectives' continued work to try and keep the case from growing cold.
"The police said they believed very early on that she was targeted and so do I," said Harley Feldman, Allison's father. "It's frustrating. We'd like it solved a long time ago. But I can't fault the effort (police) are putting in."
A Scottsdale police spokesman said expanding the original canvass area is common in complex investigations and the option for residents to provide DNA is voluntary.
ABC15 witnessed teams of officers walking door to door in the area near the crime.
"We document who we talk with and where, on each canvass contact," said spokesman Kevin Watts. "The DNA samples are what I stated earlier, voluntary. There is no action taken based on someone not providing a sample."
On Feb. 17, Allison Feldman was found dead in her home near 86th Street and Monterey Way.
Police said Feldman died of head trauma. According to court documents, she was found nude, and her body smelled of bleach. There was no sign of forced entry into her home, and it's believed that the person who attacked her suffered cuts to his or her hands.
Harley Feldman said the family is hosting a vigil Friday evening to keep Allison's crime in the public eye with the hope that someone with new information will come forward.
"I just want him caught and punished," he said.
The vigil will take place at 7 p.m. at Scottsdale Justice Center, near Osborn Road and Drinkwater Boulevard. Candles will be provided to those who attend.
"She was a very outgoing gentle person," Harley Feldman said. "Just the kindest person you could ever imagine.
"It's on our minds every day. It just never goes away," he said.
Police are offering a $10,000 reward for information leading to an arrest. Anyone who knows anything should contact 480-WITNESS.
