SAN DIEGO (FOX 5/KUSI) -- Authorities arrested a 31-year-old man suspected of at least 19 burglaries spanning the county from Chula Vista and Mira Mesa to Escondido and Oceanside. On Wednesday, Eugene Mendiola was arraigned in downtown San Diego for charges stemming from cases in Scripps Ranch, M ira Mesa and Rancho Bernardo. Mendiola, who faced a judge Thursday in Vista for his accused involvement in North County crimes, pleaded not guilty.   “I am very happy just to be able to tell these neighbors and victims of this that we no longer have to worry about him coming around and doing this again to us,” said Fay’s Diner owner Joshua Anderson. Fay’s Diner in Scripps Ranch was one of three businesses targeted March 15 and one of seven that week alone. Authorities say Anderson’s video shows the masked burglar smashing the front door then calmly walking into his restaurant and forcing the register open before running out and doing the same to two restaurants next door. “It’s horrible. What are you supposed to do when you see this and you realize you can’t clean up the glass and you realize, 'I have 15 employees that can’t go to work,'” Anderson said. “We have 300 to 400 people a weekend, what do I do? Then you have to just sit in it.” The cases being investigated by San Diego police include: March 15: Fay Diner March 15: Isabella's Mexican Food March 15: Pizza at the Ranch March 16: Pho Hoang Express March 16: Fine Indian Cuisine March 16: Pailin Thai Café March 18: Best Pizza and Brew ...read more read less
