Boise police say 56-year-old David Szwec, who was reported missing by his family late last week, walked into the Ada County Sheriff's office Monday morning to tell everyone he was fine.

Police officials have not released any information as to where Szwec was over the last three days. His family reported him missing Friday after he left to go shopping.

Here is the previous story about the family's search for Szwec.

The family of 56-year-old David Szwec has put up hundreds of fliers in the Boise area and searched almost non-stop since he failed to return home Friday.

"We're offering a $500 reward for information that leads to finding him," said his daughter-in-law, Alexandra Szwec.

David Szwec was last seen just before 10 a.m. Friday, when he told family members that he was going to buy a screwdriver set from the Sears store at the Boise Towne Square mall. He was driving a white 1996 Chevrolet C15 pickup truck with Ada County license plate: 1ACP233.

Ken Buell, Szwec's brother-in-law, said he reviewed in-store camera footage of the store entrance Szwec would have likely used but did not see him. He said store receipts did not show that he had purchased the screwdriver set he'd talked about.

"It's 99 percent, he didn't make it" to the store, Buell said. "If he was there, he didn't buy that item."

Szwec is married and has two grown children. Buell said the Szwec family gathered at his Boise home for Thanksgiving.

"He had plans to go to the movies last night with his wife and a couple of friends," Buell said Sunday afternoon. "Everything was fine."

Szwec worked in construction for 30 years but has done window installation in recent years, Buell said. The men had looked through holiday ads Thursday, and Szwec had talked about wanting to buy a screwdriver set that was on sale Friday at Sears.

Szwec is not known to go off on his own without notifying any family members, but to be sure they have checked out his favorite camping and fishing sites in Boise County.

"It's very unusual for him. He's not the kind of man who would make a story up and go out of town," Alexandra Szwec said.

Szwec's family said he doesn't suffer from any known mental conditions, such as depression. He does takes medication for high blood pressure, so his family is concerned that he might have become disoriented from a stroke or heart attack while driving.

Szwec has a cellphone. When family called it, it rang and rang at first — then later went to voicemail. It's an older phone, so Verizon wasn't able to "ping" it right away to determine where it was last on but phone company officials have said they will try to do that Monday or Tuesday, Buell said. Szwec didn't have a credit card, but he did have a debit card. It has not been used, Buell said.

"We're beside ourselves," Buell said. "We're running out of places to drive to. We can't find his truck."

Szwec is 5'3", 135 pounds. He has blue eyes, brown hair and a goatee. He was last seen wearing a dark brown shirt, blue jeans, and a black fleece jacket.

Anyone with any information about David Szwec's whereabouts is urged to contact non-emergency police dispatch at 377-6790.
