Where did the hostage-taking happen?

Early Friday afternoon police surrounded an engineering building after receiving reports that a gunman was inside. The standoff lasted for hours, then SWAT teams heard a gun shot and they decided to enter the building. On the second floor, they found that the gunman had shot himself in the head. They also saw that a male hostage had been killed by a shot to the chest. Another hostage, a woman, was unharmed, but had been restrained with duck tape.
