A hiker who went missing while ascending a peak in Arizona has been found dead, authorities said Wednesday.

Joseph Reed, 46, was last seen on Picacho Peak at around 12 p.m. Tuesday by other hikers in the area, the Pinal County Sheriff's Office. Picacho Peak is located within Picacho Peak State Park about 75 miles southeast of Phoenix.

Reed’s vehicle, however, was found in the parking lot near the trailhead on the following day, according to authorities. 

Authorities initially launched a search for another man who the vehicle was also registered to, but later learned that Reed had entered the park using a pass issued to the man, AZFamily reported.
