Worker kills supervisor in shooting at Dallas office building
An office building in Dallas has been declared safe after an incident in which a man shot his female supervisor dead before turning the gun on himself.
Assistant Police Chief Randy Blankenbaker said the names of those involved will not be released until relatives have been informed.
It is not known what kind of business operates in the office, which is in a multi-story building in the northern part of the city.
Mr Blankenbaker said the man was a current worker in the office, and there were witnesses to the shooting who were not injured.
At the height of the incident, television footage showed a heavy police response, including a Swat team, at the building.
A broken window could be seen on one of the upper floors of the mirrored tower.
Mr Blankenbaker said a police officer had to shoot a glass entry door to access the office where the shooting occurred, but no other shots were fired by police.
An officer suffered minor injuries from broken glass during the entry.
Witness Bailee Christian told KXAS-TV that she heard two gunshots - one while she was in the building and the other after her office had been evacuated.
She said: "It was very intense in the moment, very scary."
