SHOW LOW, AZ - Pinal County Sheriff's Department and Valley family members are frantically searching for a 58-year-old man who disappeared the afternoon of July 25 under strange circumstances.
Jeffrey Block had been traveling with his large, white wolf-mix dog with blue eyes named Blue in a white 2005 Dodge Ram SLT pickup trick.
His brother, Dan, said that he was last heard from during a phone call around 3 p.m. to his father, Sherwin, while driving to Show Low from his home in Apache Junction.
The phone call with his father was broken up by poor service, but Jeffrey told him that he was west of Show Low and wouldn't be able to make it to the 5 p.m. dinner they had scheduled. He reportedly said that he wouldn't be back before 7 p.m. either.
Jeffrey said that he would call his father back because of the poor service, but no one has heard from him since the phone call.
His father believes that he may have gone to collect money from a possible Craigslist sale and that it was supposed to be a quick trip.
"Every hour I try to think how this could happen, but I just don't have any idea," said Jeffrey's father Sherwin Block.
"We have even wondered if he had any personal issues that we might not know about, but we just can't think of anything," Sherwin said.
No one is completely sure why Jeffrey took the last-minute trip to Show Low.
Jeffrey was supposed to go to fishing in Colorado the following morning with his father who lives in Phoenix.
Pinal County Sheriff's Office said that Jeffrey was not on any known medications and doesn't appear to be suicidal or at any risk of harming himself.
The family and officials have contacted various police departments, jails, hospitals and other departments in hopes of finding Jeffrey.
Friends describe Jeffrey as 5 feet 10 inches tall and approximately 185 pounds. He was traveling with a large white wolf-mix dog who answers to "Blue."
He was driving a 2005 white Dodge Ram SLT pickup truck with Arizona license plate number 975-SNR.
