(CNN)Police in a Baltimore-area community have shot and killed an African-American woman after a standoff at an apartment complex, police said.
A child was injured in the Monday shootout, and a man was apprehended.
Around 9:20 Monday morning, three officers went to serve arrest warrants on a man and a woman in Randallstown in Baltimore County, Maryland.
The man was wanted for assault, while the woman, who has been identified as 23-year-old Korryn Shandawn Gaines, was wanted on a bench warrant for failing to appear in court to face "an array of traffic charges, including disorderly conduct and resisting arrest," the Baltimore County Police Department said in a statement. The charges against Gaines stemmed from a traffic stop in March, police said.
Upon arriving, the officers heard the voices of a male, female and children inside the apartment.
They waited outside the door for about 10 minutes, Baltimore County police Chief Jim Johnson said during a Monday press conference. Then, one officer obtained a key to the apartment.
Shotgun, standoff
Upon opening the door, they saw Gaines, 23, aiming a shotgun at them. The officers retreated and called for tactical backup.
"My personnel showed great firearms restraint during this dialogue," Johnson said.

At around 3 p.m., after hours of a standoff, the woman threatened officers verbally and with the weapon, according to the police account.
One police officer fired a single shot, to which the suspect fired back. Officers responded with further shots and the woman was struck. A 5-year-old child in the apartment also was hit in the crossfire.
The officers will be placed on administrative leave, which is standard procedure in officer-involved shootings, according to police. Their names will be released around Thursday morning, as dictated by the Baltimore County Police Department's contract with its union, the department said in a news release.

Gaines was killed, and the boy is being treated for non-life threatening injuries in an area hospital.
It is unclear, police say, whether the child was struck by Gaines or police.
There was also uncertainty about whether the police, which are phasing in body cameras for officers, have footage of the standoff. A spokeswoman who addressed reporters after Johnson said the department was looking to see if any officers were wearing a camera.
The man, who was wanted on an assault warrant, fled the apartment with a 1-year-old child and was apprehended. He is in custody. The police could not confirm the relationship of the two children to either suspect.
'Feisty' but 'respectful'
As the region still reels from the death of Freddie Gray, the 25-year-old Baltimore resident who died on April 19, 2015, after suffering a spinal injury while in police custody, anger against police violence remains high.
Gaines' uncle Jerome Barnett, 44, told the Baltimore Sun that his niece "was feisty, but she was smart and she was respectful."
"My niece is a good person; I never knew her to be a rowdy person," Barnett told the paper.
CNN affiliate WBAL-TV reports the case is the county's third officer-involved shooting of 2016 and the first fatal officer-involved shooting.
