A string of business burglaries in several Northeast San Diego neighborhoods has left business owners and police shaken. Business owners believe the same person may be responsible for the murders.

Surveillance video from Perfect Pizza in Rancho Bernardo shows a suspect wearing a hoodie making his way through the front door around 4 a.m. Monday.

The suspect first abandoned a cash register full of cash, then dragged the safe out the front door.

Hector Davila’s daughter received a cell phone alert from smart cameras at the store. They called the cops as they watched helplessly from home as the crime unfolded.

“First you’re offended, then you’re full of anger and rage because you’re violated,” said Davila, the owner.

Davila’s business is not the only one targeted.

San Diego police say they are investigating whether the same person entered Subway and Todo Sushi on Carroll Canyon Road in Scripps Ranch around the same time Monday morning. They also look into whether the person is responsible for previous break-ins.

Earlier this month, surveillance video from Yogurt Heaven in Scripps Ranch shows a thief entering the store with a sledgehammer. It happened on October 10th. The suspect was wearing a red hoodie and dark pants.

He is similar to the suspect caught on camera using a sledgehammer to break into Ponce’s Mexican restaurant in 4S Ranch around 3:30 a.m. on Oct. 18. Two other businesses, including Mostro Coffee, were also targeted on the same day.

When NBC 7 showed Davila the video of the suspect in the 4S Ranch murders, he said, “He looks just like him, the person who came in here.”

Davila says Monday was the second time his business and others in Rancho Bernardo have been broken into in the past six weeks. The first for him was September 13.

Although the suspects were able to drag the safe into their getaway car Monday, Davila says there was no money inside.

He says that while they haven’t taken a toll on the stores’ profits, he says the rising costs of door repairs are hard to swallow for his 4 1/2-year-old family business, which employs some of his children.

“That $1,500 could have gone to one of my kids as a week’s pay,” Davila said.
