'My heart was beating so fast': Witness tells of Wal-Mart car-attack horror

As he does almost every Sunday, Raymond Raborar was shopping in Wal-Mart in San Jose, Calif. on Sunday, while his mother was nearby at church.

But instead of having a peaceful shopping trip at the store at 777 Story Road, Raborar witnessed – and videotaped – a bizarre and violent scene on Easter Sunday, as his mother prayed at Iglesia Ni Cristo Church a few blocks away.

A driver, identified Monday by police as Haamid Ade Zaid, 33, of Seaside, allegedly drove a red Oldsmobile Cutlass into Wal-Mart's beer display before grabbing a blunt object – perhaps a metal pole – and began beating customers Sunday about 11:15 a.m.

"My heart was beating so fast," Raborar, a 28-year-old San Jose caregiver, told NBC Bay Area on Monday. "People were screaming and starting to run. It was really loud."

At first, he thought the crazy scene may have been started by some sort of terrorist.

Raborar, who was at the pharmacy desk of Wal-Mart when the car smashed through the store, caught the event on video, which he shared with NBC Bay Area.

The video shows a hectic scene, with people lying on the ground and Walmart employees doing their best to keep calm, and shooing gawkers away.

"Out, out! All the customers out!" an employee is heard yelling. A few people on Raborar's YouTube channel wrote to him that their uncle, or their grandfather, were pictured injured in the video.

Customers helped subdue Zaid – who police now say was high on drugs – until officers came to arrest him and book him in county jail.

At least four people were reported injured, not by the car, but by flying debris, according to San Jose Fire Capt. Reggie Williams.

Zaid was arrested on four counts of assault with a deadly weapon, hit and run, and being under the influence of drugs. Police said they had no specific motive for what happened.

Zaid's mother, Rosemary Zaid, of Seaside, did not want to speak on camera on Monday.

But she told NBCBayArea.com that there is no explanation for what her son is accused of doing.

Rosemary Zaid, however, described her son as an "excellent student" who attended Seaside High School and now lives in San Jose, where he owns his own auto restoration business and several properties.

"This isn't him, this isn't him, this is not what he's like," Rosemary Zaid said. "He's a good man, a business man. He's never done drugs."
