In Pursuit With John Walsh: Nimrod Guerrero is accused of murdering his girlfriend and her 17-year-old daughter

This week on In Pursuit, John Walsh is joining in the hunt for Nimrod Perez Guerrero, who is accused of a barbaric murder in Monrovia, California, in December 2018.

A mother and daughter were discovered dead in their apartment after police officers visited their home to conduct a welfare check.

Found on December 5, 41-year-old Cecilia Meza and 17-year-old Kelsey Meza were both strangled to death, according to a coroner Kelsey had also suffered “blunt head trauma.”

They are thought to have lain dead for a few days before being discovered. The main suspect remains Cecilia’s supposed boyfriend Nimrod Guerrero who was living in the apartment at the time. He vanished from the scene and still remains at large.

He is believed to have lived with the Mezas on and off for many years. At the time of the crime, the sheriff’s office stated that there appeared to be no motive for the killings.

Guerrero, who is known to often go by the alias David Gonzalez is described as Hispanic with brown eyes and brown hair. He is in his mid-30s, is 5 feet 8 inches tall, and weighs approximately 200 pounds.

Police believe he is most likely to be either in Phoenix, Arizona or still in the Los Angeles area.
