Wichita ? A Wichita teenager pleaded guilty Friday to capital murder for plotting with two others to kill a pregnant 14-year-old girl.

Everett Le Gentry, 17, told Judge Greg Waller during his arraignment that the girl’s boyfriend had requested the killing because her family had wanted him prosecuted for statutory rape or some other crime.

The body of Chelsea Brooks, who recently graduated from a Wichita middle school, was found last month in a shallow grave in neighboring Butler County.

Elgin “Ray-Ray” Robinson Jr., 20, and Theodore Burnett, 49, are charged with capital murder and kidnapping. Robinson, who allegedly impregnated the girl, also is charged with three counts of sexual intercourse with a child under 14 and one of violating a protective order the girl’s mother obtained for her in February.

Gentry told the judge the killing began with a discussion he had with Robinson about picking Chelsea up and having her killed. He said Burnett offered to do it for $500.

The judge asked Gentry why Robinson wanted the girl killed.

“He said she was pregnant with his baby,” Gentry replied.

The girl’s parents and about 18 relatives and friends listened, some holding hands and many dabbing their eyes. Gentry’s relatives also were in the courtroom watching tearfully.

Gentry said he picked Chelsea up June 9 at a skating rink and dropped her off at his sister’s house. He then picked up Burnett and returned to get Chelsea. While she was still inside, he also got shovels.

They drove toward Andover, with Chelsea in the front seat and Burnett in the back seat, Gentry said. Before reaching Andover Road, Burnett reached from behind and strangled Chelsea with a wire or cord, Gentry told Waller.

Burnett took the body out of the car to a spot behind some trees, while Gentry used the shovel to free the car that had become stuck on a dirt road. Gentry said he then began digging a hole. Burnett put the body in the grave and covered it with dirt, he said.

The teenager entered the plea during his arraignment in adult criminal court. Gentry earlier had waived his right to a hearing in juvenile court over whether he should be prosecuted as an adult.

Under a plea agreement, Gentry said he would testify against the two other defendants. As part of the deal, Gentry would receive life in prison and could be eligible for parole after 25 years. Because of his age, he is not eligible for the death penalty.

Sentencing was set for Aug. 24.
