Updated at 7:20 p.m. March 8: Revised to include the identities of the officers involved.

Officers fatally shot a man Feb. 27, bringing to a bloody end a manhunt that began with a deadly shooting Tuesday morning at an Uptown Dallas apartment building.

Officers were called about 10:15 a.m. and found Nancy Churchwell, a 52-year-old apartment employee, dead at the Northend complex near the Perot Museum of Nature and Science.

The suspect was thought to be a former security guard at the building, Deputy Chief Thomas Castro said.

Authorities found Marlon Smith, 29, three hours later in the 2100 block of Hulse Boulevard.

Dallas police Chief U. Renee Hall said Smith exchanged gunfire with two Dallas officers and a U.S. marshal before he was shot and killed. No officers were injured, but a police car was damaged.

"Obviously, it doesn't sit well," Hall said. "It disturbs us as a community as a whole if we hire individuals to protect us and they turn around and become individuals that put us in harm's way."

Curtis King, who has lived at the complex for about 12 years, said he went downstairs to pick up a package and found the building surrounded by police.

Officers told him someone had been shot. Apartment employees told him it was a female manager who was known to stock the lobby with treats for the residents and was quick to address their concerns.

"She's an amazing, amazing person," King said. "This is bizarre."

Residents gathered outside the complex, exchanging information and stories about Churchwell.

"This is incredible," said attorney Hunter Polvi, who rode his bike over to eat lunch at home but couldn't get to his apartment. He said one of the guards warned him about a week ago to be on the lookout for a former security guard who might pose a threat.

Police remained at the apartment complex through the afternoon.

Officers found Smith in the 2100 block of Hulse Boulevard about 1:30 p.m. as he came out of a car with a gun, Hall said.

They exchanged gunfire, and Smith was shot and killed, police said. He had a prior history of unlawful carry of a weapon and drug possession.

One other person was in the car with Smith during the shootout. That person was injured but did not have life-threatening injuries, Hall said.

The officers involved in the shooting were identified March 8 as Senior Cpl. Jason Kennedy, a 19-year member of the force, and Senior Cpl. Kurt Hibbets, who has been with the department for 22 years.

The name of the U.S. marshal who was also involved has not been released.

Glen Anderson, Smith's uncle, said the father of six had fallen on hard times after losing his job at Northend and was trying to get his job back.

"He was just going through some stuff," Anderson said. "I hate what happened. It's a terrible event."

He said he would have preferred that his nephew turn himself in to authorities to "face your medicine, take your punishment."
