Modesto police on Tuesday made the first arrest associated with a triple homicide in March.
Malissa Boldroff, 20, was arrested on suspicion of being an accessory to murder, said Modesto police Lt. Rick Armendariz, because she gave conflicting alibis for a person of interest in the murders: her boyfriend, Armando Ose-gueda.
Edward Reinig, 31, Alyxandria Tellez, 19, and David Siebels, 16, were shot to death inside a two-story house in the 700 block of North McClure Road near Creekside Golf Course on March 3.
Siebels' sister and the sole survivor in the home, now a 19-year-old woman, was the alleged victim of torture about a month before the slayings.
The men charged with the torture are Osegueda and Richard Garcia, 31, the 19-year-old's ex-boyfriend.
Boldroff was questioned multiple times about Ose-gueda's whereabouts the night of the murders and has given conflicting and misleading statements to detectives, Armendariz said.
Investigators said they believe Boldroff is intentionally providing false information to mislead and cover up facts about this homicide and the people involved.
Tuesday afternoon, she went to Stanislaus Superior Court, where Osegueda had appeared on an unrelated case.
Detectives approached Boldroff at the courthouse and asked her to again answer questions about the night of the murders. She again gave conflicting statements and this time was arrested on suspicion of being an accessory to murder, police said.
