Lt. Alex Arendt of St. Joseph County Metro Homicide Unit said the teen, identified as Aaron Trejo, 16, of Mishawaka, Indiana, was arrested Sunday.

The body of Breana Rouhselang, 17, a cheerleader and football team manager at Mishawaka High School, was discovered by authorities Sunday morning in a dumpster behind Pasquale Rulli Pizza in Mishawaka, just a block away from where she lived with her biological mother.

Breana’s stepmother, Nicole Rouhselang, told reporters on Sunday that Breana had been about six months pregnant at the time of her death. It is presumed that the baby has died as well.

Her family called police about 4.30 am Sunday after they ‘got the feeling that something wasn’t right,’ Arendt said.

Arendt said that Breana knew Trejo, who also attends Mishawaka High School, from the football team, but the extent of their relationship was under investigation.

The two teens, who lived near each other, were Facebook friends, but Trejo listed himself as ‘single’ and Breana did not have her relationship status posted.

Police haven’t released details about a possible motive and an autopsy is being planned to determine Breana’s cause of death.

The St. Joseph County prosecutor’s office said Trejo is being held on a preliminary murder charge and that formal charges were expected Monday.

WTHR reported that Trejo is likely to be charged as an adult.
