The family of Brian Keith Awalt is sure something bad has happened to him since he disappeared nearly six months ago, because, they say, the Spartanburg man has everything to come home for. His mother and common-law wife Awalt
describe Awalt as a hard-working breadwinner who provided for his family, loved special occasions and cherished his baby girl, who was 3 months old when her father disappeared July 12.
Since he was last seen, Awalt has turned 30, the holiday season has come and gone, and his only daughter has started walking. Those closest to him can't imagine him not calling home if he had anyway to reach a phone. "I feel positive something isn't right," said his mother, Nan Penketh. "If he was well and everything was all right, he would definitely have called home by now."
Awalt and his common-law wife, Teresa K. Longshore, 37, lived at B-2 Woodside Apartments on Fernwood-Glendale Road. They've been together for five years and have a 9-month-old daughter, Jessica Breanne Awalt. Breanne is a feminine form of Brian that Awalt invented, Ms. Longshore said.
Awalt was reported missing to the Spartanburg County Sheriff's Office on Aug. 15, sheriff's spokesman Mike Little said.
Awalt was last seen about 2 p.m. on July 12. That day, he sold plasma at a local plasma center, then
left his house with a strange man, Little said. "We don't have anything to go on as far as foul play is concerned, but because of the length of time he's been missing, there is a possibility that foul play might be involved," the sheriff's spokesman said.
The last person who saw Awalt was 17-year-old Brian Bryson. Bryson lived in Woodside Apartments at that time. He said he had
never seen the man whom Awalt left with that day. "He was real scraggly-looking and unkempt," Bryson said. "He had long hair and looked like a hippie. But Brian didn't seem like anything was wrong. He was jovial and seemed happy.
He got in the man's car and they drove off."
Ms. Longshore said
Awalt didn't take any clothes with him when he left, and he
didn't have any money other than the money he made selling plasma that day. He had
just been laid off from his job at Metal Builders and
was working odd jobs to support the family. "He idolized our baby," Ms. Longshore said. "He begged for her for three years. He desperately wanted a girl. He wouldn't even leave her with his own mother because he couldn't bear to be away from her. "
His birthday is on Oct. 17, and mine is Oct. 15. We always celebrated them together. It's always been a joyous time. We even thought about getting married on Oct. 16, so all the dates would be together," Ms. Longshore said.
Awalt is 5 feet 11, and at the time of his disappearance he
weighed about 160 pounds and had a moustache. He has
blue eyes and light-brown hair. He has a
two-inch scar on his upper left arm and a scar on the right side of his face under his eye. Anyone with information about Awalt is asked to call the sheriff's office.
