Carla Burgos, the sister of slain Monica Beresford-Redman, met with Los Angeles District Attorney Steve Cooley on Monday for several hours, RadarOnline.com learned exclusively.
Monica's husband Bruce Beresford-Redman is a suspect in her murder, which occurred in Mexico.
Accompanied by her high-powered and newly hired attorney Alison Triessl, Burgos met with Cooley for approximately three hours. Sources close to the case told RadarOnline.com exclusively that Burgos and her attorney want "assistance" with the case from the L.A. district attorney's office.
Monica and Bruce,who have two children, had been staying at the Moon Palace resort in Cancun when Monica was reported missing. Her body was found in a sewer at the resort. Bruce was released from Mexican custody but remains under investigation. He is not allowed to leave the country, according to investigator Veronica Acacio.
