Reward increased in Scottsdale woman's unsolved murder

Investigators increased the reward to $10,000 for information that leads to the arrest of a suspect in an unsolved February murder in Scottsdale.

Allison Feldman, 31, was murdered in her home near Pima and Thomas roads some time between late February 17 and early February 18 of this year, according to officials.

Police say that the attacker left Feldman's home around 1 a.m. on February 18 with her iPhone 6 and some credit cards. Investigators believe Feldman's killer lived in the area.

Officials said the attacker took Feldman's Tiffany bracelet, and they are asking anyone who might have received a Tiffany bracelet from a man who lived in that area in the past four months to contact authorities.

Police have the killer's DNA, which will make it easier to link or to exclude anyone from the case, according to investigators.
