PARADISE VALLEY, AZ - Police said Tuesday five people have been arrested in connection with the murders of a Paradise Valley couple.
The suspects have been identified as 31-year-old Michael Lee Crane, 27-year-old Brittnay Beinhauer, 29-year-old Kelly Steward, 29-year-old Shawn Nicloy and 26-year-old Danielle Rossman.
One of the arrests was reportedly made as recently as Monday evening. Sources tell ABC15 there could be additional arrests as the investigation continues.
Lawrence Shapiro, 79, and his wife, Glenna, 78, were found bound, shot, and burned beyond recognition in the master bedroom of their home, near 40th Street and Stanford Drive, on January 30th.
"There is no evidence at this time that leads us to believe that the Shapiros were specifically targeted," Police Chief John Bennett confirmed at a Tuesday news conference.
"Investigators continue to examine evidence and have submitted high priority evidence to crime laboratories for analysis," Bennett said. "Evidence recovered thus far includes statements by individuals now in custody and recovery of the murder weapon."
Sources tell ABC15 the murder weapon is a small caliber handgun.
A motive in the case is unclear at this time, according to police.
The investigation started when police responded to the Paradise Valley residence that morning after a car belonging to the couple was found burning behind the Goodwill store near 7th Street and Union Hills in north Phoenix.
When police arrived at the Shapiro residence, it was on fire.
The couple was positively identified through dental records.
Sources tell ABC15 that critical forensic evidence was recovered from the Shapiros’ home and the location where their car was found burning. Sources also said jewelry and other items were stolen from the home and the couple's credit cards or other financial documents might have been used after their deaths.
Officials said police are still searching for a sixth suspect, though the woman is not as central to the case. Silent Witness reportedly played an important part in breaking the case.
Crane faces two murder charges, in addition to kidnapping, armed robbery, arson and burglary charges. The remaining four suspects reportedly face theft or trafficking in stolen property charges.
ABC15 spoke with Crane's mother who said she was shocked at the developments and said her son is being held on $3 million bond.
Phoenix police have launched an investigation into the possibility that some of those arrested might have been involved in a Phoenix fire that left 56-year-old Bruce Gaudet dead .
A memorial service for the Shapiros was held Monday at the historic Orpheum Theater.
The Shapiro family issued a statement Tuesday on GlennaLawrenceShapiro.com , saying:
We appreciate the work of Paradise Valley Police Department and the other agencies that have worked on this investigation. We are eager to see the perpetrators brought to justice so that they can be prevented from doing further harm, and the community may have some peace of mind. However, our foremost concern at this moment is coming to grips with the loss of our parents, which is very difficult. We are grateful for the outpouring of love and support from so many and are touched by the tributes that have been shared with us.
Lawrence Shapiro, a well known philanthropist, had a career as a doctor in the Valley for more than 45 years. Glenna has been the CEO of the National Kidney Foundation of Arizona.
