Sean Garber, owner of Grade A Recycling, said Megan Washburn, John Loucks and a third woman, whose family had asked not to release information about her, were still missing.
Garber said Washburn was a young mother and "a wonderful young lady".
He said three customers, including a 3-year-old child, died at the business.
Two of those customers were identified by a family friend as Louisnes "Lou" Fedon and his granddaughter, Kimberly Asa, 3, ABC News reported.
They "were simply in the wrong place at the wrong time, becoming victims of this catastrophic and unforeseen accident", according to a GoFundMe account set up to support Fedon’s teenage children.
Fourteen people, including the three crew members of Flight 2976, have been confirmed dead.
An engine of the MD-11 McDonnell Douglas aircraft detached as the plane was taking off from Louisville’s Muhammad Ali International Airport on the way to Honolulu, creating a fiery scene as the wreckage hit two businesses south of the airport, including Garber’s.
The NTSB is still investigating.
Louisville Mayor Craig Greenberg said in an update yesterday officials thought the death toll would remain at 14.
• Sandy Springs-based UPS announced it is grounding its entire MD-11 fleet after the fatal Louisville crash, which involved one of its MD-11 planes.

The company said the grounding would take effect immediately and had been recommended
by Boeing, the aircraft’s manufacturer. — Lexington Herald-Leader
