Police had been called to the home around 6 p.m. Friday before returning early Saturday morning.They also said they heard shouting just before police arrived the second time."All I heard was either talking or just loud voices and my dog was barking so we told him to knock it off. We went to sleep and then a few minutes later the police surrounded the whole neighborhood," Channie Lim said. "There was crying out loud, shouting and stuff and so that woke us up."Anyone with more information was asked to contact the Santa Ana Police Department.
