A high school football player from Indiana says he stabbed his classmate in the heart after finding out she was pregnant with his child and it was too late to get an abortion, police said.

Aaron Trejo, 16, from Mishawaka, is charged with one count of murder and one count of feticide for allegedly stabbing 17-year-old Breana Rouhselang to death, the South Bend Tribune reported.

Police arrested Trejo early Sunday after cops found Rouhselang’s body covered in a trash bag in a dumpster behind a restaurant near her home. She was six months pregnant. Rouhselang, a cheerleader at Mishawaka High School, was also the football team’s manager.

Rouhselang’s mom called the police to report her daughter missing at 1 a.m. Sunday. She told cops her daughter left her house Saturday night to talk to Trejo but never returned.

During questioning, Trejo initially told police he was supposed to meet with Rouhselang to talk about the pregnancy at the alley behind her house but she never showed up, according to an arrest affidavit.

Upon searching the alley behind Rouhselang’s house, cops found glasses and a bloody stocking cap. They eventually discovered Rouhselang’s body behind Pasquale Rulli’s restaurant a block from her home.

Cops took Trejo to the St. Joseph County Metro Homicide Unit for questioning, and he denied seeing Rouhselang the night of her murder for a second time before eventually confessing. He told police that neither he nor Rouhselang wanted to have the baby.

“I took action … I took her life,” he said, according to an affidavit obtained by the Indianapolis Star. He admitted thinking about killing Rouhselang for about a week. He stabbed her in the heart with a knife from his house, then put her body in a black trash bag and threw her in a dumpster, Trejo told the police.

Trejo told cops he went to the St. Joseph River, where he threw the weapon and Rouhselang’s cellphone “as far out into the river as he could.” An autopsy found that Rouhselang died from multiple stab wounds and strangulation from a scarf around her neck. The autopsy confirmed the pregnancy.

Trejo will be tried as an adult. He faces up to 65 years behind bars on the murder charge and another 16 on the feticide charge. His arraignment was scheduled for 1 p.m. Tuesday.

Rouhselang’s classmates learned of her death Sunday night during a football team banquet. On Monday, 200 students at the school left class and observed a moment of silence for Rouhselang at the school flagpole.

Friends of Rouhselang’s family set up a GoFundMe page to help them cover funeral expenses.
