During the ceremony Metrolink executives honored the victims’ families.

“It has taken a lot from us. That’s emotionally, financially, in every way,” said Mackenzie Souser, who joined her mother Claudia Souser to honor her father Doyle Mackenzie who died in the tragedy. “It’s hard. When I graduate college he won’t be there. In a couple days my 23rd birthday he won’t be there. And when I walk down the aisle he won’t be there and it’s always going to be a void that nobody else can fill.”
