According to court documents, Hartford Police have a witness who knows what led up to the shooting that killed Cordova. The witness told detectives that on June 9, he was visiting a cousin's house on Heath Street before the shooting took place. Hartford police are searching for the person responsible for firing the shots that killed 56-year-old Sylvia Cordova as she was cooking dinner in her Sisson Avenue home Wednesday night. The documents say two people were arguing outside of the home when the witness went outside and started arguing with the two people he knows as "Diego" and "Menor." Not long after the argument, "Diego" pulled out a gun and pointed it at the witness. The two then took the witness's dirt bike, according to the documents.
