UPDATE - July 18: According to a news release, the Yavapai County Sheriff's Office received a credible tip on Thursday, July 14, that Terry Z. Ferrell was seen recently at a Camp Verde area restaurant.
Deputies obtained video of the event and, according to his girlfriend, the subject seen by the restaurant employee was not Ferrell.
The YCSO still is seeking help from the public in locating Ferrell. Recent area search missions around his home have been unsuccessful.
Prior reports - July 14: The Yavapai County Sheriff's Office is seeking the public's help in finding Terry Zane Ferrell after it received a tip that Ferrell was seen Sunday at a restaurant on Highway 260 just off Interstate 17 in Camp Verde.
"Deputies received a tip about a possible sighting of Ferrell at a restaurant in Camp Verde and are following up on some leads," said Dwight D'Evelyn, spokesman for the YCSO. "We want people to keep a look out for him and call us if they see him."
Anyone who has seen Ferrell, especially in the Camp Verde area, since he left his home on Sunday, July 3, is asked to call YCSO immediately at 928-771-3260 or Yavapai Silent Witness at 1-800-932-3232.
Ferrell is 5-foot-9, weighs about 160 pounds, and has blue eyes, blonde hair with evident balding on the back of his head, and Fu Manchu-style facial hair. No clothing description is available other than he occasionally wears a tan baseball cap.
"The deputies are talking to those witnesses right now, so I don't have additional details to release yet," D'Evelyn said. "But we will release updates."
Deputies have been searching for Ferrell since he was reported missing by friends and family on Tuesday, July 5, after he walked away two days earlier from his home in the 11700 block of Dusty Trail in Coyote Springs, D'Evelyn said.
Ferrell left behind his cell phone and his vehicle, D'Evelyn said.
YCSO also confirmed Wednesday that Ferrell likely possesses a handgun and is in a despondent mental state, which precluded the initial use of unarmed search and rescue volunteers to find him, D'Evelyn said.
Forest patrol deputies, who are armed, have been looking for Ferrell since he was reported missing and conducted several flyovers of the area near his home and Mingus Mountain but saw no sign of him, D'Evelyn said.
On Tuesday, YCSO used three volunteer quad teams under the supervision of armed deputies to search in the wilderness area north of Ferrell's home to Mingus Mountain from 7 a.m. to 6 p.m., but Ferrell was not found, D'Evelyn said.
The two-day delay in reporting Ferrell missing to YCSO has made the search more difficult, and deputies have interviewed family, friends, and co-workers to determine where he might be, D'Evelyn said.
