One woman died and eight other people were wounded -- including three children -- after two gunmen dressed in all black opened fire at a gender-reveal party in Ohio, officials said Sunday.
A group of friends and family gathered Saturday night to learn the biological sex of a woman's upcoming birth when two men entered through the front door and began shooting, Colerain Township police Chief Mark Denney told CNN.
According to Denney, the shooting lasted "maybe a minute or two" before suspects fled the scene on foot.

Police said Autum Garrett, 22, died in the shooting. The eight other victims -- including three children, ages 8, 6 and 2 -- suffered non-life threatening injuries.
A family member told WLWT that the pregnant woman throwing the party was among those injured and lost her baby after suffering a shot to the leg.
After shots broke out, a bystander sitting in a nearby vehicle phoned 9-11 and told dispatchers she saw two men enter the residence.
"Two guys just came in and shot people in the house," she said, according to the Cincinnati Enquirer. "There was little kids hurt and everything. I was sitting in my car. They just ran in and started shooting. There's a pregnant girl here."
Another caller also reported there had been two shooters.
"I just seen two people walk by," a man told the operator, per ABC affiliate WCPO. "I looked outside, next thing I know they just ran in and just started shooting."
Denney said police have yet to identify the two gunmen.
According to Denney, there were no indications of forced entry by the gunmen. He also said the gunmen's motives are unclear to police at this time.
"We don't know if they were targeted, or this was intended for someone else," Denney said.
