CBS 5 News has confirmed there have been arrests in connection with the murders of a prominent Paradise Valley couple, according to the town's vice mayor.
Mary Hamway told CBS 5 News she learned of the arrest around 11 a.m. Friday.
Sources told CBS 5 News the arrests were reportedly made Thursday night. It's unclear if more are expected.
The bodies of philanthropists Dr. Lawrence Shapiro, 79, and his wife, Glenna, 78, were found in their burning Paradise Valley home Monday.
A source close to the investigation told CBS 5 that the public played a critical role in facilitating the arrests.
Paradise Valley Police released a statement Friday saying they would not be releasing any information Friday regarding the homicide.
Residents in the area told CBS 5 News they were glad the threat they've been living under for the past few days may now be over. Because those involved in the murders were still on the loose residents said they were keeping their guard up and making sure to take extra care when locking up their homes.
One resident said more than anything she is glad to know that the Shapiro family may get some justice.
"I was just concerned for the family such a tragic way to die and who could be so angry to take some one's life in that manner?" said Barbara Higgins, a resident.
Lawrence was a doctor and served on several medical organization boards. He was also a founding member of Physicians for the Phoenix Symphony.
His wife, Glenna, served three decades as the CEO of the National Kidney Foundation.
