A Tongan man in the United States said a stray bullet could have killed his wife after it hit his son’s van on Tuesday.

The bullet went right through the window of the van and hit the driver’s seat.

Sione Vaha’i of San Bruno believed if some one was sitting on the driver’s seat when the bullet struck it could have gone straight through that person’s chest.

Vaha’i said his wife returned from work at about 9pm. She parked the van before she went inside their house.

Two hours later the stray bullet hit the vehicle.

He said Police knew where the bullet came from and they were investigating.

Vaha’i claimed the shooting came after gunfire was exchanged between a neighbour and a shooter.

He claimed the neighbour was trying to hide by his van before the bullet hit.

Vaha’i said the van was not targeted during the incident.
