FLORENCE, S.C. -- A 30-year police veteran was killed and six of his comrades wounded when a man opened fire from inside his home on deputies who came to serve a search warrant, authorities said. The shooting continued for hours as the man barricaded himself inside with children, firing from a distance at officers who came to help.

The slain officer, Terrence Carraway, 52, of Darlington, had just been honored for his 30 years of service with the Florence Police Department.

CBS News correspondent David Begnaud reports that Florence Police Chief Allen Heidler was unable to fight back tears describing Carraway. Heidler called him and the rest of the wounded officers "family."

"I want you to pray for the family who lost the bravest police officer I have ever known," Heidler said.

Authorities had to use a bullet-proof vehicle Wednesday to recover the wounded, and the shooter finally released the children as he was taken into custody, authorities said.

"Officers went there unknowing the firepower the suspect had," Florence County Sheriff Kenney Boone said at a news conference. "Fire was being shot all over. The way this suspect was positioned, his view of fire was several hundred yards. So he had an advantage. The officers couldn't get to the ones who were down."

The violence stunned people already dealing with record flooding from Hurricane Florence. Both the sheriff and police chief both cried as they spoke to reporters after the standoff.

The suspect opened fire on three Florence County deputies who had come to serve a search warrant around 4 p.m. Wednesday, Boone said.

Then, he shot four Florence city police officers, one fatally, as officers from all over swarmed in to help, Heidler said.

CBS affiliate WBTW-TV, citing Chief Deputy Glenn Kirby, reports that a 20-year-old male inside the home was also shot and is still alive.

Boone credited his department's military equipment for enabling them to pull the wounded from the field of fire.

"Thanks to our MRAP, armored personnel carrier, we made sure all the officers that were shot were protected and brought for medical atttention," he said.

Officials refused to say why they were serving a warrant. They did not name the suspect. They also did not identify the wounded officers or describe their conditions.

Condolences and outpourings of support rolled in.

President Trump tweeted his "thoughts and prayers," saying "We are forever grateful for what our Law Enforcement Officers do 24/7/365."

"This is simply devastating news from Florence," Gov. Henry McMaster tweeted. "The selfless acts of bravery from the men and women in law enforcement is real, just like the power of prayer is real."

Thom Berry, spokesman for the State Law Enforcement Division, said the agency had sent crime scene technicians to assist officials in Florence but at this time had not been requested to help with any investigation.

Boone said investigators from Richland County would help. He did not say why he wasn't using state police like most law enforcement agencies do in officer shootings in South Carolina.

Authorities said the shootings happened in Vintage Place, an upscale neighborhood in the western part of the city.

Bobby Goin stood outside waiting for police to let him back to his home, where his wife and granddaughter could hear the gunshots.

"Surprised is probably an understatement," said Goin, who has lived in the neighborhood for 20 years. "The worst thing that goes on around here is that someone runs a stop sign and it gets posted on Facebook."

This is the second shooting of multiple police officers in South Carolina this year. In January, a 47-year-old former banker shot four officers in York County, killing one, after his wife called 911 to report he beat her. Christian McCall pleaded guilty and was sentenced to life without parole.

Florence, a city in South Carolina's northeastern corner home to roughly 37,000, sits at the convergence of Interstates 95 and 20. It's the largest city in the region known as the Pee Dee, where flooding from Hurricane Florence devastated areas to the east and south.
