The best friend of a 22-year-old Las Cruces woman who died after a stabbing Saturday morning told KFOX14 she died after trying to break up a fight between two friends.

"I can't believe this happened," Vanessa Montoya said. "It's a nightmare."

Montoya said she knew Delia Vasquez since elementary school and said they've been best friends ever since.

Montoya described Vasquez as a loving mother to her 7-year-old son and a woman who never really got into any trouble.

"We were together every day," Montoya said. "We were really close friends."

Vasquez died Sunday after police say she was stabbed by 23-year-old Jacklyne Legarreta.

Montoya said it happened after Vasquez tried to break up a fistfight between Montoya and Legarreta.

"She was just bleeding everywhere from her chest," Montoya said. "She was all, 'Jackie stabbed me. Jackie stabbed me.'"

Montoya said despite their fight that night, Legarreta is also her close friend and dated Montoya's brother. She even lived in Montoya's home along with her two children.

"She's a totally different person when she's sober," Montoya said. "She's the nicest thing ever, but when she's intoxicated, it gets out of hand."

According to the police report, Legarreta denied ever fighting with Vasquez that night but did admit to fighting with Montoya.

Police believe Legarreta went back into the apartment after the stabbing to clean off and get rid of evidence before police arrived.

"One night of drinking led to something so wrong," Montoya said.

Legarreta is charged with one open count of murder and tampering with evidence.

Montoya said she's left to grieve over the loss of two loved ones.

"Two families are involved in this, and three little babies lost their mothers that night," Montoya said.
