A teenager in Indiana pleaded guilty Wednesday to killing a cheerleader who had been pregnant with his child, reports said.

Aaron Trejo, 17, made the plea deal in connection with charges of murder and killing a fetus for the December 2018 slaying of 17-year-old Breana Rouhselang, according to Indiana’s WSBT-TV.

The high school football player told police that the two had an argument about Rouhselang’s pregnancy. Trejo believed she waited too long to tell him and it was too late for her to get an abortion.

“I took action … I took her life,” Trejo told South Bend Detective Gery Mullins, according to charging documents obtained by Fox News.

He also told police that he put her body in a dumpster behind a restaurant.

Rouhselang was six months pregnant at the time of her death.

Trejo faces up to 80 years in prison at his sentencing in January.
