Cops Shoot Baby Used As Shield

LAPD Says Father Fired First After Hours-Long Standoff

(CBS/AP)  It was unclear who fired the shot that hit the girl, but officers were struggling with the thought that they killed a baby, McDonnell said.

"The officers are taking it very hard," he said. "Anytime you have a baby killed, it takes its toll."

The standoff began at around 3:50 p.m. when officers responded to an area in South Los Angeles west of Watts after residents reported an armed man standing near an intersection with a toddler and behaving erratically and aggressively.

There were three exchanges of gunfire between police and Lemos, who was about 35, McDonnell told reporters. In the final exchange, at around 6:20 p.m., Lemos held the girl as he shot.

"We did everything we could to hold our fire," McDonnell said.

At one point, Lemos retreated into an apartment building, where police said he held the girl hostage.

Police called in a SWAT team and tried to speak with the man; when they at one point attempted to help a neighbor escape the area, he fired at them and they fired back, McDonnell said.

Under police regulations, officers may only fire "when it reasonably appears necessary" to protect themselves or others from death or serious injury.
