PHOENIX  — A former Peoria resident visiting family in the Valley was found dead  after she went  missing on a hike Friday in north Phoenix, and her death appears to be heat-related, authorities said.

Phoenix Fire Department officials said Jessica Christine Lindstrom, 34, went hiking around 8:30 a.m. Aug. 4 and was declared missing about nine hours later by Phoenix police.

Fire Department Capt. Scott Douglas said drones and technical rescue teams were used during a five-hour search before Lindstrom’s body was found on a remote trail on the north side of the Deem Hills Recreation Area.

Douglas said it will be up to the Maricopa County Office of the Medical Examiner to determine a cause of death, but preliminary information suggests Lindstrom was overcome by the heat while hiking.

Authorities said Lindstrom, who formerly lived in Peoria, was a registered nurse in Oregon and was visiting family.
