State troopers continue to block off every street leading in to the area damaged by Tuesday's explosion at the West fertilizer plant.
The lack of access is frustrating for people who have loved ones missing.
Saul Saldivar came to West from Portland, Ore., searching for his 58-year-old father Marino Saldivar who lived on the bottom floor of the apartment complex that was destroyed in the blast.
Thursday night, the Waco Tribune reported crews found a man and a woman on the bottom floor, but they have not been identified.
The Texas Department of Public Safety is now confirming 12 casualties, but there is still a lot of rubble to sift through.
Saul Saldivar said he has called every hospital in town and can't find his father. But he's still holding out hope.
"Everyone's really worried. Everyone's trying to call, trying to get information and we still haven't been able to," said Saldivar.
He says the last time he talked to his dad was Tuesday morning. Saldivar and his uncle are walking around West with missing posters hoping maybe someone will have information about his father.
