PITTSBURGH - Pittsburgh police said they had serious concerns when an armed man took a business owner hostage in a downtown high-rise office building — and not just because he had a knife.
The suspect, 22-year-old Klein Michael Thaxton, made Facebook posts during the five-hour ordeal Friday, authorities said, and they feared that responses from friends, family and others might goad him into violence.
In the end, police say, Thaxton surrendered peacefully and released businessman Charles Breitsman.
Now police believe that Thaxton might have chosen Breitsman because he spotted a smartphone and computer in his office and saw a high-profile opportunity to express himself on the social networking site, Chief Nathan Harper said.
Thaxton was arraigned early Saturday on felony charges of kidnapping, aggravated assault and making terroristic threats. He remains jailed on $1 million bail.
Harper said authorities might never know the reason Thaxton decided to take a hostage.
"We will leave that to the mental professionals to figure that out and get the man some help," Harper said. Thaxton will automatically receive a mental health review because of the charges.
Thaxton told police he left a halfway house about 3 a.m. Friday carrying a kitchen knife, hammer, cellphone and charger. After meandering through various neighborhoods, Thaxton arrived downtown at about 7 a.m. and briefly considered attacking two separate traffic officers with the hammer so he could steal their guns, police said.
