Pittsburgh police say they had serious concerns when an armed man took a businessman hostage in a downtown high-rise building. But not just because the suspect had a knife.
What also worried police was that the suspect, 22-year-old Klein Michael Thaxton, was posting messages on Facebook and getting responses from family, friends and others.
While most of those messages Friday expressed love for Thaxton or urged him to surrender, police feared others might set him off.
In the end, police say, Thaxton surrendered peacefully, and the businessman wasn't hurt.
Thaxton was arraigned early Saturday on felony charges of kidnapping, aggravated assault and making terroristic threats. He remains jailed on $1 million bail.
