Mother, teen daughter killed in Monrovia were strangled, coroner says

MONROVIA, Calif. -- Coroner's officials say a woman and her teenage daughter found dead in an apartment east of Los Angeles were strangled, and the girl also suffered head trauma.

The bodies of 41-year-old Cecilia Meza and 17-year-old Kelsey Meza were discovered Dec. 5 when police in Monrovia were asked to check on them after the girl had missed several days of school.

Their suspected killer remains at large Sunday. Los Angeles County sheriff's officials say Nimrod Perez Guerrero should be considered "armed and dangerous."
