Doctor on condo search team details efforts on the mound: "Targeted" searches, not random

Millions have seen the images coming out of Surfside, Florida — mountains of concrete, steel and debris at the site of what used to be the ocean-facing Champlain Towers South condos. But Dr. Christopher Valerian, a medical manager for a search and rescue team that was deployed to the collapse site, told CBS News the pictures don't do it justice.

"Everything from the particles floating in the air that you are walking through. At the end of the day, you are all dusty. The smells which are indescribable and stay with you," said Valerian of New Jersey Task Force One. The group consists of dozens of members who have years of experience digging through piles of debris, but Valerian said the team has had a difficult time both physically and emotionally working in Surfside.
