The former fiancée of a California theater actor who murdered an Afghanistan War veteran and his friend in 2010 was convicted Wednesday of lying to police in an attempt to protect him from prosecution, PEOPLE confirms.
Rachel Buffett was found guilty of two counts of being an accessory after the fact in the murders of veteran Sam Herr, 26, and 23-year-old Juri “Julie” Kibuishi, a college student studying fashion. Both were fatally shot by actor Daniel Wozniak.
During the trial, prosecutors alleged that Buffett purposefully lied to police on multiple occasions and changed her story to protect Wozniak, the Orange County Register reported.
Prosecutor Matt Murphy tells PEOPLE Buffett lied to police at least 20 times, saying, “She lies repeatedly. There are little lies and big lies.”
Buffett’s defense attorney David Medina argued that his client had no knowledge of the murders.
“She did not know what Dan’s involvement was,”
