Anchorage police are looking for two missing vulnerable men in separate cases Saturday night, expressing concern for them ahead of expected low temperatures.

David Nealy was last seen leaving his home on the 3500 block of Stanford Drive, off Lake Otis Parkway near 36th Avenue, between 4:30 a.m. and 9 a.m. on Nov. 18, according to police spokesman MJ Thim.

“[Nealy] left for unknown reasons and hasn’t returned,” Thim wrote in a statement. “He suffers from health issues including schizophrenia and dementia.”

Nealy, 61, stands about 6 feet tall, weighs 190 pounds and has hazel eyes and balding gray hair; he uses dentures, but may not be wearing them. He was last seen wearing light-colored Dockers, a red hoodie and a red-and-black plaid jacket.

Police are also continuing to look for 53-year-old Joe “Grant” Orand, who has bipolar issues and was last seen Nov. 18 according to his family. He had left a cab on Tudor Road at Checkmate Drive at about 4:15 p.m. that afternoon, after he was discharged from Providence Alaska Medical Center and sent home; he was driven back to Providence after he didn’t have keys to his home.

According to police, Orand stands about 5 feet, 8 inches tall and weighs about 150 pounds; he has green eyes and blond-and-gray hair. He was last seen wearing a black winter jacket and black pants.

There are no connections between the two cases, Thim said, except the date both men were last seen and concern by police for their safety amid subzero temperatures forecasted overnight in parts of town.

“It’s unusual for them to be gone – both of them have left their homes before and always returned, but they’ve never been gone this long,” Thim said. “Between these two men being gone this long and the weather and the cold temperatures tonight, detectives are hoping the public can find them.”

Thim said police haven’t had contact with either man, but urge anyone who sees them to call APD dispatch at 907-786-8900.
