It wasn't until 3:15 p.m. that police started escorting most residents back to their homes on Cashel Circle, but there were a few residents who had to wait before returning home. The neighborhood was flooded for most of the day with local police and bomb squads from the ATF and Travis Air Force Base.
At about 10:20 a.m. an elderly man on Cashel walked down his driveway to pick up his Sunday paper, but what he didn't know, was that there was some sort of bomb wrapped inside. When he grabbed it blew up. The loud boom brought out neighbors who found the man bloodied and lying on the lawn in front of his house. The victim was taken by helicopter to UC Davis Medical Center in Sacramento and authorities say his injuries are not life threatening.
"He had cooked breakfast for us and he was waiting for us to arrive. His newspaper was on his coffee table, so either it wasn't necessarily his newspaper, but it was a newspaper there or it could have been a package," said Sharon Sanchez, the victim's daughter-in-law.
"I was in the backyard playing basketball with my son and I heard a big explosion and I thought it was a shotgun…it was a pretty loud noise, I mean, it was loud," said Dan Garner, a neighbor.
The city also made automated calls to everyone in Vacaville warning them not to pick up their newspapers and to call police if they noticed any suspicious packages. On Sunday afternoon, police were running around answering calls from residents concerned they may have seen something suspicious, but at this point, authorities say no other explosive devices have been found, but they are asking residents to be vigilant.
Authorities believe this was isolated, they have no indication this man was specifically targeted and they have no suspects.
There were some rumors that this was some sort of acid bomb, but that's not the case. Authorities are also not calling it a pipe bomb. And at this point they don't know exactly what type of device exploded.
