Taptejdeep Singh's family said the married father of 2 was trying to warn colleagues that there was a shooter when he was gunned down.

"Even in the last moments, he wasn't looking for his own safety, per se, he was trying to save people. That's who he was," his cousin said.

Paul Delacruz Megia started working with the VTA in 2002. At the time of his death, he was an assistant superintendent in service management.

"Paul was a wonderful husband & father who was full of love, jokes, energy for life and always up for new adventures," his wife said.

Jose Dejesus Hernandez III began working for the VTA in 2012.

His ex-wife, Sarah Raelyn, described him as the calmest and most level-headed person that she had ever known and he spent his life "worshipping the Lord and just helping people."

San Jose City Council Member Raul Peralez said he was longtime friends with Michael Joseph Rudometkin, whom he referred to as "Mikey" in a post mourning his death.

"There are no words to describe the heartache we are feeling right now, especially for his family," Peralez wrote.

The Medical Examiner-Coroner also identified the following individuals as victims of the shooting:

• Adrian Balleza
• Timothy Michael Romo
• Abdolvahab Alaghmandan
• Lars Kepler Lane
• Alex Ward Fritch

A vigil will be held for the victims Thursday at 6 p.m. in San Jose.
