(FOXNEWS) — An Alabama family recounted to FoxNews.com a chilling airport encounter they had last month with the man they believe went on to gun down 12 people at a Washington military facility, and said the confrontation was triggered by the hearty laugh of a 75-year-old matriarch.

“We were just laughing and talking and he came over and said we were laughing at him,” Rosalind Baugh told FoxNews.com, speaking of Aaron Alexis, the troubled former Navy Reservist and government contractor who went on a shooting spree in the Naval Sea Systems Command headquarters in southeast Washington Monday.

Since the shooting, in which Alexis was killed by police, several reports have surfaced about his anti-social behavior, mental problems and record of arrests for gun offenses. As soon as he was identified as the shooter, Baugh and other family members present at Norfolk Airport for the Aug. 4 incident have been reliving the frightening encounter daily.
