Four young children held hostage by an Orlando man during a dramatic standoff with police Monday have been found dead, authorities say. Gary Lindsey Jr., the suspect, was also found dead at the scene Monday night, apparently of a self-inflicted gunshot wound, Orlando Police Chief John Mina said at a late-night press conference. Authorities had spent the better part of the last 24 hours pleading with Lindsey to let the children go, after he barricaded himself in an apartment with them following a confrontation with police over a domestic-violence call. Two of the children were believed to belong to Lindsey, while the other two were thought to belong to his girlfriend. The children were aged 1, 6, 10, and 11. Lindsey also allegedly shot a police officer during the domestic-violence call, leaving him in critical condition.
