MOUNDRIDGE, Kan. (AP) — A woman charged in connection with the deaths of three people north of Wichita has pleaded guilty.

Myrta Rangel entered her plea Monday to federal charges for her role in the October 2016 killings of Travis Street, Angela Graevs and Richard Prouty. The charges involved Rangel giving a gun to her boyfriend Jereme Nelson, who's facing capital murder and first-degree murder charges in the slayings, the Wichita Eagle reported .

Police found the victims dead outside a home where Street and Graevs lived in rural Moundridge. The couple's toddler was found alive and unharmed in the house.

Nelson, Rangel and her estranged husband in Mexico had arranged to sell methamphetamine to Street, according to Rangel's plea agreement. The meth shipments would initially go through Nelson before reaching Street, but the drugs eventually bypassed Nelson and went directly to Street.

Rangel gave Nelson a handgun because she knew he was going to Street's house to collect a drug debt, the agreement said. Nelson drove to Street's home, where he shot all three victims in the head. Prouty was at the house to buy meth, according to the plea.

The couple was captured in Mexico and turned over to U.S. law enforcement.

Rangel pleaded guilty to transferring a firearm she knew would be used to commit a drug trafficking crime and to giving a firearm to a convicted felon. She's scheduled for sentencing Sept. 19, the same day Nelson is due in court for a preliminary hearing.
