(Casa Grande, AZ) — Three teens were arrested late last week in connection to the shooting death of a Casa Grande man who was gunned down on July 18.

The suspects, each 18-years old, face murder and robbery charges in the death of 35-year-old Benjamin Harmer, who was shot and killed at the intersection of French and Ocotillo streets last month.

Jeramiah Anthony Rivera, 18, was arrested last Thursday in Globe and is being held at the Pinal County Adult Detention Center in the county seat of Florence, police said.

Miguel Ángel Castillo-Tapia, 18, was arrested on Friday in Toltec, and Alfred Reyes, also 18, was taken into custody on Friday in Casa Grande. The CGPD said these two were to be transported to the Florence facility Friday afternoon.

Police had opened an investigation and had previously asked the public to be on the lookout for a late-1990s model "grey or primer" Chevrolet Tahoe they had connected to the early-morning shooting. An official statement from Chief of Police Mark McCrory credited and thanked the Casa Grande community for its help and support.

"Once again, the Casa Grande community has shown its commitment to helping us safeguard this community," McCrory said in the media release. "I cannot begin to thank you all for the support you have given our officers and detectives investigating this crime."

Public records accessed by NewsBreak show Rivera has appeared in Pinal County municipal courts before, but he does not appear to have any history of run-ins with law enforcement beyond traffic violations. These violations include speeding, driving without vehicle registration, and driving without an adult passenger present while on a learner's permit. Neither Reyes nor Castillo-Tapia appeared in a search of court records.

Police indicated that they will continue to investigate the circumstances surrounding the shooting. An alleged motive is unknown at this time.
