Police officers are under intense criticism in Dallas tonight after a woman appears to have been murdered in her home while on the phone with a 911 operator, begging for police to come help her.

According to the Dallas Morning News, Deanna Cook called 911 at about 10:55AM last Friday to say she needed help. The call lasted 11 minutes, but it's what happened next that's caused so much outrage: police weren't dispatched until more than 30 minutes later.

So while the call was classified as urgent, it wasn't given the highest priority, and so police officers didn't arrive at Cook's house until almost 50 minutes after the call was initially placed, according to the newspaper.

Officers checked the outside of the house and spoke to neighbors, but found no signs of foul play and left. Two days later, Deanna Cook was found dead in her bath tub by her sister Karletha Cook-Gundy, who comes OutFront tonight with her other sister Valecia Battle.

Curtis Horne was riding a city bus outside the Empire State Building in Manhattan this morning when he suddenly heard shots ring out.

Standing just a few yards from the shooter, he reacted with heroism and bravery, shielding a young girl and her mother from the chaos, and he comes OutFront tonight.

Gunfire erupted on the streets of midtown Manhattan this morning as a man opened fire outside the Empire State Building.

58-year-old Jeffrey Johnson shot a former colleague on the sidewalk before engaging in a shootout with police officers that resulted in his death and injuries to 9 other bystanders, some of whom may have been accidentally shot by police officers returning fire.

The victim is 41-year-old Steven Ercolino, according to the State University of New York, where he was a 1992 graduate. New York City Police Commissioner Ray Kelly is OutFront tonight with more details.
