According to the police department, on July 28 at 2:31 p.m., officers responded to a call regarding a stabbing incident at the intersection of Fourth Avenue and Spencer Street.
When they arrived, they found Thayer and she was pronounced dead at the scene, Shakopee Police said.
Police said they believe the suspect and victim knew each other and that it "wasn't a random act."
KMSP-TV, citing a search warrant, reports Thayer's body was found next to a car and her decapitated head was next to her body. Police officers reportedly found a knife in a trashcan near the crime scene as well as a sheath for a knife.
Saborit allegedly told Shakopee Police he and Thayer spent the earlier part of the day in the park and were going to a court appearance for him, but she allegedly tried breaking up with him, KMSP reports. Saborit allegedly told police Thayer had "gone too far" and he killed her.
Her coworkers at Dollar Tree allege domestic abuse was a problem in Thayer and Saborit's relationship.
One of Thayer's coworkers at Dollar Tree told KMSP Thayer asked if she could sleep at their homes to get away from Saborit. One person said, "She came around 1:30, 2 in the morning and knocked. She goes, 'Can I sleep here tonight? I'm afraid he is going to get up and start in again.'"
