SCOTTSDALE, AZ — Police have taken the man accused of killing a 67-year-old man at his Scottsdale home into custody, according to the Scottsdale Police Department.
Officers initially responded to a welfare check at 67-year-old Frank Quaranta's home near 68th Street and McDowell Road on Monday, September 1.
After not being able to make contact with Quaranta, officers forced entry into the home and found his body inside.
Scottsdale police had named Matthew Dieringer as the suspect in the case, warning the public that he should not be approached.
Police say Dieringer has a history of experiencing homelessness.
According to Scottsdale police, "detectives learned that for the past few months, the victim had provided Matthew Dieringer with a place to stay at his home."
On Saturday, a citizen reported seeing Dieringer around 13th Street and Indian School just before 9 a.m. Phoenix police responded and took Dieringer into custody.
ABC15 has learned that Dieringer has a past criminal history, including a conviction in Colorado for killing his roommate's dogs in 2020.
They add that Dieringer has been described as "manipulative and charismatic," often befriending others to help him with a place to stay.
Scottsdale Police Chief Joe LeDuc shared the following statement:
"I want to thank the men and women of the Scottsdale Police Department who worked tirelessly on this case. Their persistence and dedication made this outcome possible. I am also grateful to the members of our community who stepped forward after seeing our news release and provided the information we needed. I also want to thank the Phoenix Police Department for their swift and decisive action. This was a true team effort, and it shows what can be accomplished when our employees, our community, and our law enforcement partners work together. Let this also be a clear message: if you commit a violent crime in Scottsdale, we will use every resource at our disposal to find you, and you will be held accountable.”
Dieringer will be booked into the Maricopa County Jail for his probation violating, officials said. Additional charges are pending.
