Trujillo stabbed Andersson 25 times with the 5-inch stiletto heel of a blue-suede pump in a late-night altercation at Andersson's condo.
Trujillo claimed self-defense, saying that Andersson attacked her, though friends said the professor wasn't prone to bouts of rage.
"Dr. Andersson probably was a nice guy, but what he did that night can't be dismissed because he was a nice guy," Trujillo's defense attorney argued.
In a police interrogation video after the incident, Trujillo said that she performed CPR and called 911 after she saw that Andersson had stopped attacking her.
"What she doesn't say in this video is as important as what she did say," the prosecutor said. "When did we hear that Ana Trujillo was in fear for her life? No one said anything about her ever being in fear for her life."
Trujillo faces life in prison.
