A gunman who was dressed in a UPS uniform opened fire at United Parcel service, killing three people and then himself on Wednesday morning.
The gunman put the weapon on his head and pulled the trigger when police caught him, Police said.
In a statement, UPS said, “UPS confirms there was a shooting incident involving six employees within the company’s facility in San Francisco earlier this morning”.
It further reads, “We understand that there are four deaths, although some individuals were transported to the hospital and we are unsure of their status at this time”.
“It was like tat, tat, tat, tat, tat, tat, tat”, said Raymond Deng, who live across the street from the warehouse.
