Police were reporting the shooter was “neutralized.” Our latest information is the shooter shot and killed himself.

That shooter had been in a standoff with Dallas police for hours in the El Centro college parking garage. Negotiators said they were getting nowhere with him.

The report he shot himself came at 2:30 a.m., but the tactical squad was seen leaving the garage and police in the area began to relax about half an hour before that.

Three other people have been arrested in connection with the ambush of 11 police officers that took place about 9 p.m. on Thursday evening.

People who work downtown are asked to stay home on Friday.

County Judge Clay Jenkins said the following buildings will be closed:

The George Allen Courts Building

The Dallas County Records Building

Old Red

The Dallas County Administration Building

El Centro College and the Dallas Holocaust Museum will also be closed.
