The young women were bound with duct tape. Neiman's friend was raped by all three men, authorities said.
Bornt and his son and the two women then were driven to rural Kay County, police said. Clayton Lockett told the captives he was going to kill them all, the surviving victims said.
Clayton Lockett told Neiman to get out of her pickup, and he shot her twice when she failed to give him her keys and the alarm code for the pickup, police were told.
Mathis told police he dug a grave for Neiman and buried her with Alfonzo Lockett's help.
The rape victim and Bornt told police they and Bornt's son then were brought back to Bornt's home.
The three men left in Bornt's pickup. The car Clayton Lockett drove to Perry apparently was stolen and was impounded by police when officers spotted it parked outside Bornt's duplex.
Jasper Lockett, 16, said his brother Alfonzo told him that Clayton Lockett threatened to kill him and Mathis if they went to police.
Police said Mathis and Alfonzo Lockett admitted they took part in the assault on Bornt and helped tie up the two women and drive them to rural Kay County.
Alfonzo Lockett showed authorities where Neiman was buried. Her mouth still was bound with duct tape, according to court records.
Clayton Lockett was released from prison last August. He was sentenced to four years in prison after pleading guilty in 1996 in Kay County to a charge of conspiracy to commit embezzlement.
In 1992, he pleaded guilty in Kay County to burglary and knowingly concealing stolen property. He received a seven-year prison sentence. Earlier that year, he pleaded no contest to two counts of intimidating state witnesses.
Jasper Lockett said Clayton Lockett picked up his brother Thursday night to take him to an Enid nightspot. He said he tried to tell Alfonzo, who recently was released from a juvenile detention center, not to go.
"He didn't leave with the purpose to kill somebody," Jasper Lockett said. "He said if they knew they were going to do that, he wouldn't have left. He was in the wrong place at the wrong time. It was a bad choice."Archive ID: 765808
