Michael C. Sontoya and Gabriela Romo had rough sex in the early hours of Sept. 30 after hooking up, drinking together and going back to the duplex Sontoya rented on S. Robert Street on St. Paul's West Side.
Romo was only 4-feet-11 and 100 pounds. That rough sex caused, among other injuries, a 14-inch internal laceration that damaged her spleen, diaphragm and liver, jurors heard Friday on the first day of Sontoya's trial in Ramsey County District Court.
Romo bled to death; rigor mortis was setting in by the time an ambulance was called at 6:48 a.m., according to testimony.
Sontoya, 32, is charged with first-degree murder while committing criminal sexual conduct and second-degree murder while committing first-degree assault.
In his opening statement, Assistant County Attorney Daniel Vlieger, who is prosecuting the case with County Attorney Susan Gaertner, showed photos of bloodstains on a bare mattress and the carpet, blood that someone appeared to try to clean up on the walls, blood on a stack of clothes in a plastic bag and blood and vomit in a corner.
Defense attorney Anthony Torres told the jury that Sontoya never lied about having sex with Romo that night. But there is no evidence he assaulted her sexually or otherwise and he shouldn't be convicted of killing her, Torres said.
The two had been friends since the second grade. They dated in high school, then went their separate ways. Romo had four children with her longtime boyfriend; Sontoya had three with his longtime girlfriend.
At the time of Romo's death, both had ended those relationships and had reconnected, Torres told the jury. She was 31 and living with her parents in St. Paul.
