Ruiz's former girlfriend testifies

Posted: Updated:

Pasco, WA-Prosecutors are questioning the memory of the former girlfriend of a man on trial for five murders.

On the witness stand today, Diane Garcia Rosas testified she didn't see Vicente Ruiz or his cousin on the night 23 years when five men died in a Pasco auto body shop.

Prosecutors, however, say they have taped recordings of Garcia telling the lead detective that Ruiz and his cousin showed up at her home on the night of the killings.

Ruiz's cousin, Pedro Mendez Reyna, pleaded guilty to the murders in the mid 1990s, and is now serving life in prison.
