This one gives me the chills: Phoenix couple's murder puzzles police year later. Who can put the pieces together?
In July 2014, William Singer, 81, and his wife Barbara Singer, 64, were found murdered in their north Phoenix home near 35th and Grovers avenues. The couple, both with backgrounds in the medical field—William as an EMT instructor and Barbara as a nurse practitioner—were known for their community involvement and had no apparent enemies. 
On July 2, 2014, a healthcare worker arrived at their residence for a scheduled appointment with William but received no response. Concerned, authorities were contacted, and upon entering the home, they discovered the couple deceased, with evidence suggesting they had been dead for several days. Investigators noted the absence of forced entry, indicating the Singers might have known their assailant. 
Surveillance footage from June 28, 2014, showed both William and Barbara making late-night ATM withdrawals around 10:30 p.m., an unusual activity for the couple. Detectives observed that William appeared to be under duress during the transaction. This led to speculation that the couple may have been coerced into withdrawing money before being taken back to their home, where they were subsequently killed. 
Despite extensive investigations, including interviews and the release of composite sketches of potential suspects, no arrests have been made, and the case remains unsolved. The Phoenix Police Department continues to seek information from the public to bring justice for William and Barbara Singer.
