Dallas Mayor Eric Johnson took to twitter to voice his support for the victims and their family.
“I am heartbroken by the horrific mass shooting today in San Jose,” Johnson Wrote in a May 26 Twitter post. “The victims and their loved ones, the people of San Jose, and my good friend Mayor @sliccardo are in my thoughts. Dallas stands with you all.”

The suspect allegedly set fire to his home before going to his workplace, according to ABC 7 News. Investigators discovered Molotov cocktails, twelve firearms and over 20,000 rounds of ammunition in the damaged home. A search of the suspect’s locker at his workplace contained materials to that could be used to create explosives.
“It is clear that this was a planned event and the suspect was prepared to use his firearms to take as many lives as he possibly could had sheriff’s deputies not made entry to stop his rampage,” the department said, ABC 7 News reported.
