A 30-year-old woman died one day after eight people were shot at a party held after a Martin Luther King Jr. Day parade, Florida police said Tuesday.

The woman and her 6-year-old daughter were attending a party at Ilous Ellis Park in Fort Pierce when shots rang out at around 5:30 p.m. Monday, the St. Lucie County Sheriff’s Office said.

The woman, who has not been publicly identified, died of her injuries Tuesday morning at the hospital. It's not clear whether her daughter was injured.

"Now what was a shooting investigation has turned into a murder investigation," Sheriff Ken Mascara said.

Seven other people were shot, Mascara and Chief Deputy Brian Hester said. Four others were injured trying to escape the violence.

Police have not publicly identified any suspects. They said the shooting was the result of a dispute between two rival gangs. Hester said over 50 shell casings from three different-caliber weapons were recovered at the park.

Hester asked anyone with information to come forward and warned that anyone "hiding, supporting, protecting" the people responsible will be arrested and charged.
