An Oklahoma man has pleaded guilty to a felony charge of attempted burglary at a Westar Energy substation in December.

Timothy Weaver, 32, of Dell City, Okla., drove to Wichita “specifically to steal copper from Westar,” according to a news release from District Attorney Marc Bennett. Weaver, along with Dusty Drake of Oklahoma City and Kristie Parsons of Moore, Okla., removed the padlock to the substation but was apprehended by Sedgwick County sheriff’s officers before completing the burglary, according to district court documentation.

Drake is scheduled for a jury trial on July 7, and Parsons is awaiting trial, though the trial date was not available Tuesday afternoon, said Dan Dillon, media coordinator for the DA.

Weaver awaits sentencing on July 17.
