Dr. Marc Larsen, medical director of the emergency room at St. Luke's Hospital, which is near the scene of the fire, said they had treated eight people, six of whom were walk-ins with minor injuries. He said two males were in critical condition and would be kept overnight. He said one had extensive burns and another had facial trauma.
Jim Ligon, a JJ's bartender, said he wasn't working Tuesday night but started getting texts and calls from co-workers minutes after the explosion. He said the incident happened during the peak of weekday happy hour, when there is typically anywhere from 15 to 45 people in the bar area as well as three to five tables of diners at the restaurant.
"JJ's has a small staff, a family feel," said Ligon, 45, of Kansas City, Mo. "You see the same 100 people all the time — a bar and restaurant for regulars. We're just really hoping we come out of here OK in terms of injuries."
Ligon said he was on his way Tuesday night to meet up with co-workers at another bar in town to talk about the incident.
The shopping area was established in 1922 by J.C. Nichols. Based on the architecture of Seville, Spain, it includes retail, restaurants, apartments and offices.
