According to Morgan Hill Police, murder suspect Martin Mendoza was “arrested at the California Mexico Border Crossing while trying to come back into the United States from Mexico.”
Law enforcement officials in San Diego County told the Morgan Hill Times last night that Mendoza was taken into custody around 2pm by U.S. Marshalls and transferred to the Imperial County Jail in El Centro, California.
Mendoza is being charged under California Penal Code Section 187 for murder in connection with the death of 18-year-old Morgan Hill woman Marissa DiNapoli, who disappeared last weekend after home security cameras recorded the accused killer and the teen descending a staircase on Saturday morning.
The following is a full copy of the statement issued this morning by Morgan Hill Police Department:
