Vice President Kamala Harris tweeted Monday that "enough is enough" in the wake of "another senseless mass shooting," and called on state and federal legislators to "step up and act."

"Parents shouldn't have to pray their babies come home same from school or a birthday party," Harris tweeted. "The majority of Americans, including gun owners, support commonsense gun safety laws. We need leaders in state houses and Congress with the courage to step up and act."

Tallapoosa County Coroner Mike Knox has identified the four people declared dead from Saturday night's shooting: 23-year-old Corbin Dahmontrey Holston, 19-year-old Marsiah Emmanuel Collins, 18-year-old Philstavious Dowdell and 17-year-old Shaunkivia Nicole Smith.

Dowdell and Smith were both seniors at Dadeville High School.

The Dadeville Police Department has "solid leads" as they search for the suspected shooter, but authorities still need help from the public, Dadeville Police Chief Jonathan Floyd told ABC News on Monday.

Floyd asked anyone with photos or videos from Saturday night's sweet 16 party to come forward.

Due to the department's manpower and resources, Floyd said the Alabama State Bureau of Investigations is taking the lead with the investigation.

An emotional Dadeville police chief pleaded for prayer for his city on Sunday and law enforcement investigators pleaded for tips from the public in finding those responsible for a shooting at a birthday party that left four dead and multiple people injured.

"The city of Dadeville is a tight-knit community, full of wonderful people. I ask you to please keep our community in your prayers. I ask you to please keep my police department in your prayers," Police Chief Jonathan Floyd said at a news conference.

Sgt. Jeremy Burkett of the Alabama Law Enforcement Agency confirmed the shooting broke out at a birthday party and asked for any witnesses to call the state police tip line.

Burkett also confirmed that four people were killed and "a multitude" of people were injured, but did not disclose the conditions of those wounded.

Burkett did not take questions during the news conference. He released no information on whether any arrests have been made in the incident.

Tallapoosa County Schools Superintendent Raymond Porter said grief counselors will be at Dadeville schools on Monday, but did not say whether any students were among the dead or injured.

The district will make "every effort to comfort" children impacted, said Porter.

"Don't lose sight of the fact that those are the ones most impacted by this situation," said Porter, who also called on local clergy to reach out to families of those killed or injured to offer assistance.

"I'm also asking that you please do not let this moment define what you think of the city of Dadeville," Floyd said. "What we're dealing with is something no community should have to endure."
