While the search for victims continues at a fertilizer plant in West, Texas, the families of three volunteer firefighters are already facing the grim reality that their loved ones have answered their final alarm.

Brent Bridges, 18, told the Star-Telegram that his father, Morris Bridges, was told that he probably didn’t survive.

Robert and Doug Snokhous, brothers,  are also among the volunteer firefighters unaccounted for.

Marqee Snokhous, who lives in Florida, told reporters she spent the early morning calling every hospital in hopes of finding that her father, Robert Snokhous, and uncle were among the injured.

Her calls haven’t panned out, and as of 12:30 p.m. Thursday, she said the family still had not received confirmation about the fate of her father or uncle.

“There’s not been anything official but the mayor did call my stepmom,” she said. “He told her that he’s pretty sure that they’re both inside the business in the plant, trapped in there. And that there’s a pretty high probability that there’s no survivors there.”

Authorities have been gingerly searching the site as well as nearby buildings looking for victims killed in the blast that registered 2.1 on the Richter scale.

The West Volunteer Fire Department says it has 33 firefighters.

Among them are Mayor Tommy Muska whose helmet was blown off by the blast.

In the seconds after the explosion, a voice heard on the radio says they need as many ambulances as possible.

The West Volunteer Fire Department was established in 1894 as the West Hose Company #1. The first equipment for West Hose Co. #1 was a Hose Reel drawn by a rope tied to a volunteer’s saddle horn.
