A Transportation Security Administration branch manager has died from the coronavirus, the second agency employee to succumb to the deadly bug, officials said.

Alberto Camacho, a branch manager for the federal agency’s Acquisition Program Management office, died April 3 after contracting COVID-19, TSA officials announced Thursday.

“Every day, he worked closely with TSA’s partners to ensure the nation’s aviation security technology remained cutting edge and ahead of the threat,” a statement read. “We offer our heartfelt condolences to Alberto’s family, friends and his TSA colleagues.”

Camacho, who joined the agency in 2005, started as a training manager in San Francisco before moving on to positions in security operations and with the Federal Air Marshal Service. He last worked at the TSA Systems Integration Facility in Arlington, Virginia, where he managed the implementation of passenger and baggage technologies, agency officials said.

Camacho’s age was not immediately available, a TSA spokeswoman said Friday.

Camacho’s death follows that of Francis “Frank” Boccabella III, an explosive detection canine handler at Newark Liberty International Airport in New Jersey who died from COVID-19 on April 2.

“Frank was dedicated to protecting the traveling public with his canine partner, Bullet, a 6-year-old German Short-haired Pointer and his previous canine partnet, Zmay,” TSA officials said in a statement. “Frank and his canine partners screened hundreds of thousands of passengers, keeping them and the transportation network safe.”

As of Friday, 344 TSA employees, including security screeners, have tested positive for COVID-19. Seventeen employees have recovered, according to TSA data.
