Police conducted a ground and aerial search Thursday in three counties for two women and a girl missing since May 29.
The search was fruitless, but, weather permitting, the aerial search will continue today, said Kym Koch, Oklahoma State Bureau of Investigation spokeswoman.
Jackie Taylor, mother of Wendy Camp, said Thursday she does not have much hope that her daughter, who suffers from multiple sclerosis, is still alive.
Missing with Camp, 23, are her Camp's daughter, Cynthia Britto, 6, and Camp's sister-in-law, Lisa Renee Kregear, 22.
OSBI agents, joined by Bristow police and Creek County sheriff's officers, searched Payne, Lincoln and Creek counties, Koch said.
Taylor said Wendy's doctor feared Wendy would be either dead or in a coma without her medication.
Wendy Camp, her daughter, and her sister-in-law went to Shamrock on May 29, Taylor said. She said Wendy called her husband about from the Shamrock Cafe about 5 p.m. that Friday.
That was the last time any of Wendy's family have heard from her, Taylor said.
Koch said the three were riding home with an acquaintance when they got into an argument with the driver.
The driver dropped the three off at a Wal-Mart in Chandler between 5:30 to 6 p.m., Koch said.
Camp is 5 feet 3 inches tall, weighing about 200 pounds and has brown hair and blue eyes. She was wearing red sweat pants, a red shirt and white tennis shoes. She walks with a limp.
Britto is 3 feet tall, weighing about 60 pounds and has brown hair and brown eyes. She was wearing a pink sweat shirt, a blue and black striped shirt, light blue corduroy slacks and tennis shoes.
Kregear is 5 feet, 4 inches tall, weighing about 130 pounds and has blond hair and blue eyes. She was wearing acid-washed jeans, a yellow and white striped shirt, black ankle boots and yellow earrings.
Anyone who may have seen the three get out of a gray 1985 Audi at the store is asked to call the OSBI's 24-hour hot line at 1-800-522-8017. BIOG: NAME:Archive ID: 507216
