The suspect accused of shooting an Orlando police officer in the face and holding four children hostage for nearly 24 hours killed the children and then killed himself, police said.
Orlando Police Chief John Mina said they lost communication with Gary Lindsey about 8:30 p.m., but were still trying to end the situation peacefully.
They said Lindsey’s phone had a poor connection, so negotiators tried to get him another phone.
Once they did, SWAT team members were able to see that one of the children was dead.
Mina said the children were shot.
"Our hearts go out to the family of those four children. A long day like this is physically and emotionally draining," Mina said.
