Police continue to search for an additional suspect after nine people, including children, were shot and injured along the Hollywood Beach Broadwalk on Florida's east coast.
Four children between the ages of 1 and 17 were shot Monday night, including a baby between 15 and 18 months old, according to Hollywood police spokesperson Deanna Bettineschi.
The other five victims were adults ages 25 to 65.
The four children remain hospitalized on Wednesday, all in stable condition, according to hospital officials. The injured adults have been treated and released.
The shooting apparently stemmed from an altercation between two groups, and multiple people were detained in the aftermath, Bettineschi said Tuesday.
Two men believed to be involved in the shooting have been arrested on weapons charges, Bettineschi said. Morgan Deslouches, 18, and Keshawn Paul Stewart, 18, both face a concealed carry weapon charge in connection with the incident. Deslouches also has been charged with larceny-grand theft of a firearm and removing the serial number from a firearm, court records show.
A third suspect was taken into custody Saturday, and a fourth suspect was taken into custody Sunday, police said.
Authorities said they're still looking to identify one more person they believe was also involved in the shooting.
"No stone will be left unturned in bringing the perpetrators to justice," Hollywood Beach Mayor Josh Levy said in a statement Tuesday. "We will utilize every available resource to apprehend those responsible."
"It is completely unacceptable that innocent people spending time with family on a holiday weekend have been affected by a shooting altercation between two groups who came into our city with guns and no regard for the safety of the law-abiding public around them," Levy added.
