The man accused of murdering a beloved San Diego high school teacher and coach had a previous relationship with the victim’s current fiancée, according to court documents obtained by Team 10.

Police arrested 30-year-old Jesse Alvarez in connection with Monday’s murder in North Park.

The petition for a domestic violence restraining order filed in December 2019 showed Alvarez was the former boyfriend of Fierro’s current fiancée. Team 10 is not naming the woman.

According to the documents, the woman said she and Alvarez dated for three and a half years. She told the judge that he was stalking her after they broke up. She asked that Alvarez “leave [her] alone” and wrote that she was fearful for her safety. She named several instances where she said Alvarez stalked her, including a time where he followed her at Disneyland.

In the petition, she wrote that she had to change the locks to her door and installed security cameras. She also filed a police report when she said Alvarez attempted to break into her home. The judge dismissed her request for the restraining order with prejudice in January 2020. He wrote that she, "did not meet her burden of proof."

Michael Carini is a former classmate of Fierro who ran track with him at Cathedral Catholic High School.

“He was so kindhearted. Everybody loved him. He was not one to draw in drama or chaos or anything like that,” Carini said.

He heard about the recent engagement and was happy for his former teammate. Carini said hearing about the news surrounding Fierro’s death is heartbreaking.

“This was almost beyond belief… it seemed so surreal it couldn’t be possible,” Carini said.
