Three inmates were found dead over the weekend at Lower Buckeye Jail in Phoenix, according to Maricopa County officials. The deaths remain under active investigation, with autopsies pending to determine the time and manner of each case. The sheriff’s office says detectives are also combing through the facility as part of their probe into what happened.
Officials Investigating
A spokesperson for the Maricopa County Sheriff’s Office confirmed the three deaths at Lower Buckeye Jail and told Arizona’s Family that the Jail Intelligence Division, Special Response Team, Jail Crimes detectives and detention deputies were carrying out a full search of the jail to make sure the facility is safe, according to Arizona's Family. Authorities told the outlet they are waiting on autopsy results to clarify the timing and manner of each person’s death.
Official Records Show Recent Deaths
The sheriff’s office maintains a public "Inmate Deaths" log that lists recent fatalities by facility. That listing currently includes entries for Lower Buckeye, including a June 29 entry, per the Maricopa County Sheriff's Office. The log provides names and dates, but the agency has not publicly linked any specific entry on that list to the three deaths reported over the weekend.
Context: In-Custody Deaths Have Drawn Scrutiny
An investigation earlier this spring by Arizona’s Family found that drug-related deaths in Maricopa County jails nearly doubled in Sheriff Jerry Sheridan’s first year in office, with deaths rising from 12 in 2024 to 21 in 2025, a trend that families and advocates have questioned, according to Arizona's Family Investigates. Public records tracked by the Maricopa County Attorney's Office document in-custody incidents across years and facilities and repeatedly list Lower Buckeye among locations where fatal incidents have occurred.
What Happens Next
Within the county jail system, Jail Crimes detectives typically lead investigations into deaths. The unit’s public description explains that investigators conduct interviews, collect evidence, attend autopsies and prepare cases for prosecutors when warranted, according to the Maricopa County Sheriff's Office. The Maricopa County Office of the Medical Examiner notes that toxicology and related testing can take weeks, so official rulings on cause and manner of death may not be available for some time.
