May 5 (UPI) — One of 23 people injured in a weekend shooting at a lake party in an Oklahoma City suburb has died, authorities said Tuesday as they continue to search for a suspect.

The shooting occurred at around 9 p.m. CDT Sunday at Lake Arcadia where a group of young people were having an unauthorized party near a campground that had been advertised across social media.

Police initially said 10 people were taken to area hospitals but warned the number would rise as individuals were transported by private vehicles.

The deceased victim was identified by the Edmond Police Department as “an 18-year-old young woman.”

“Our thoughts are with her loved ones, as well as all those affected by this tragic incident,” the Edmond Police Department said in a statement.

“We thank our community and media partners for their patience and understanding as we work to confirm details and release appropriate information. This investigation is being handled with the utmost care and seriousness.”

The announcement came a day after local police announced the casualty toll had increased to 23, with injuries ranging in severity. Some suffered gunshot wounds, authorities said.

Police said they were not releasing suspect information at this time but asked members of the public with information about the shooting to contact authorities.

Edmond Mayor Mark Nash issued a statement Monday explaining that shootings such as the one on Sunday are rare for the city and “will not define us.”

“We are a strong, engaged community. We support one another, we face challenges directly and we move forward together,” he said.

“That is what makes Edmond special, and that is exactly what we will continue to protect.”
