DALLAS, Texas — A Memphis mother is in Dallas for her daughter’s surgery, and it put her just feet away from Thursday’s chaos.

Shelley O’Connor heard the echoes of about fifty gunshots from her daughter’s hospital room.

“The hospital went on lock down, and they blocked off the streets around the hospital,” said O’Connor.

She watched the mayhem play out on TV wondering where the sniper could be.

“You were looking even in corridors of the hospital at people wondering who they were, and if they were involved in anything,” said O’Connor.

She kept friends and family updated on her Twitter.

One post she asked people, “to pray for the fear here. Lots of tension.”

O’Connor said some of the victims were carried on gurneys into the hospital.

Nurses and doctors helped others get around in wheelchairs.

“A lot of procedures, MRI scans, all that kind of thing going on today that normally don’t go on in this kind of volume,” she said.

Friday morning, O’Connor said downtown Dallas was oddly quiet as people recovered from the horror.

“People were trying to bridge that gap. They were obviously trying to bridge that gap,” she said.
