HAMPTON, S.C. (AP) — Authorities in South Carolina are investigating a shooting at a nightclub early Sunday that wounded at least nine people. It was the second mass shooting in the state and the third in the nation during the Easter holiday weekend.

The shootings in South Carolina and one in Pittsburgh, in which two minors were killed early Sunday, also left at least 31 people wounded.

No one was reported killed in the violence at Cara’s Lounge in Hampton County, roughly 80 miles (130 kilometers) west of Charleston, according to an email from South Carolina’s State Law Enforcement Division, which is investigating the shooting. A phone call to the nightclub was not answered.

In Pittsburgh, two male youths were killed and at least eight people wounded when shots were fired during a party at a short-term rental property. The “vast majority” of the hundreds of people at the party were underage, the city’s Police Chief Scott Schubert told reporters. Investigators believe there were multiple shooters, and Schubert said police were processing evidence at as many as eight separate crime scenes spanning a few blocks around the rental home.

The two shootings come just a day after gunfire erupted at a busy mall in the South Carolina state capital of Columbia, about 90 miles (145 kilometers) north of Sunday’s nightclub shooting. Nine people were shot, and five people sustained other kinds of injuries while trying to flee the scene at the Columbiana Centre, Columbia Police Chief W.H. “Skip” Holbrook said Saturday. The victims ranged in age from 15 to 73. None faced life-threatening injuries.

“We don’t believe this was random,” Holbrook said. “We believe they knew each other and something led to the gunfire.”

The only person arrested in the mall shooting so far is Jewayne M. Price, 22, one of three people initially detained by law enforcement as a person of interest. Price’s attorney, Todd Rutherford, told news outlets Sunday that his client fired a gun at the mall, but in self-defense. Rutherford said Price faces a charge of unlawfully carrying a pistol because he legally owned his gun but did not have a permit to carry a weapon.

Columbia police said on Twitter that a judge agreed Sunday to let Price leave jail on a $25,000 surety bond. He was to be on house arrest with an ankle monitor, police said.

“It was unprovoked by him. He called the police, turned himself in, turned over the firearm that was used in this, and gave a statement to the Columbia Police Department,” Rutherford said, according to WMBF-TV. “That is why he got a $25,000 bond.”

Police said the judge will allow Price to travel from home to work during certain hours each day. Price is forbidden from contacting the victims and anyone else involved in the shooting.

South Carolina residents age 21 or older can get a weapons permit, which as of last year allows them to carry weapons openly or concealed. They must have eight hours of gun training and pass a background check that includes fingerprinting.

The three Easter weekend mass shootings are in addition to other gun violence in recent days. Last week, a gunman opened fire in a New York subway car, wounding 10 people. A suspect was arrested the next day. Earlier this month, six people were killed and 12 others wounded in Sacramento, California, during a gunfight between rival gangs as bars closed in a busy downtown area just blocks from the state Capitol.

One week ago, a shooting inside a crowded nightclub in Cedar Rapids, Iowa, left a man and a woman dead and 10 people wounded. And last month, 10 people were shot at a spring break party in Dallas and several others were injured as they tried to escape the gunfire.

WASHINGTON (AP) — Millions of Americans wait until the last minute to file their taxes and this year is no exception.

Monday is Tax Day — the federal deadline for individual tax filing and payments — and the IRS will receive tens of millions of last-minute filings electronically and through paper forms.

As of April 8, the IRS had received more than 103 million returns for this tax season, and it had issued more than 63 million refunds worth more than $204 billion.

For comparison, last year more than 169 million people completed an income tax return by the end of the year. That probably leaves nearly 40 percent of this year’s taxpayers still unaccounted for, with many scrambling to submit their documents by Monday.

Nina Tross at the National Society of Tax Professionals says if people haven’t filed their taxes by now, “they’re better off filing an extension.”

But, she added, “People don’t realize that filing an extension has zero effect” as long as they have paid their income taxes by Tax Day.

“An extension is merely filing a return at a later date,” Tross said. “If you rush through a return to get it out the door, and you have to amend it later, you’re more likely to get a double look from the IRS.”

“You’re much better off extending than amending,” she said.

The IRS this year is facing its biggest backlog in history. At the end of the 2021 filing season, the agency had 35.3 million returns waiting for processing. One reason is that every paper document that goes into the IRS is processed by a human, according to the IRS.

And some forms are reviewed by IRS employees and treated as if submitted on paper even if they are e-filed.

This year will be one of the most challenging for the agency, with its record low staffing numbers. The IRS workforce is the same size it was in 1970, though the U.S. population has grown exponentially and tax laws have become increasingly complicated.

The agency announced plans in March to hire at least 10,000 more workers.

Lisa Greene-Lewis, a CPA and spokesperson at TurboTax, said that if people still intend to file a return by Tax Day, “I would gather all your documents in one place so you don’t leave anything out, like W2s and 1099s.”

Important papers such as the “ Letter 6419 ” that outlines the Child Tax Credit payments a taxpayer should have received this year and the “ Letter 6475 ” for stimulus payments should also be on hand.

Greene-Lewis, who has been doing taxes for over 20 years, said “you want to report the correct amount you received so you don’t have to have to make adjustments to your refund.”

The IRS has put out some information and helpful links for last-minute filers — stressing that “taxpayers should be careful to file a complete and accurate tax return. If a return includes errors or is incomplete, it may require further review.”

Keith Kahn with the Delaware Society of CPAs said he encourages everyone to file an electronic return.

When asked whether CPAs will accept clients on Tax Day, Kahn said it’s common for people to be turned away. But for those who can get an appointment, “make sure you have everything you could possibly provide to your CPA — there’s not a lot of time to hammer out strategy or to ask questions.”

COLUMBIA, S.C. (AP) — Police have arrested a suspect in connection with a shooting at a busy shopping mall in South Carolina’s capital on Saturday that left 14 people injured.

Columbia Police Chief W.H. “Skip” Holbrook said 22-year-old Jewayne M. Price, who was one of three people initially detained by law enforcement as a person of interest, remains in police custody and is expected to be charged with unlawful carrying of a pistol.

It is not immediately known if Price has an attorney who could speak on his behalf.

Fourteen people were injured during the shooting at Columbiana Centre, Holbrook said in a news release Saturday. The victims ranged in age from 15 to 73.

Holbrook said no fatalities have been reported but that nine people were shot and five people suffered injuries while attempting to flee the mall for safety.

Police said the 73-year-old victim continues to receive medical treatment, but the other victims have been released from local hospitals or will be released shortly.

“We don’t believe this was random,” Holbrook said. “We believe they knew each other and something led to the gunfire.”

Investigators believe that at least three suspects displayed firearms inside the mall but are working to determine how many suspects fired weapons. Police said at least one firearm was seized.

Daniel Johnson said he and his family were visiting from Alabama and were eating in the food court when they first heard shots ring out and started seeing people running.

Johnson said people were screaming for their children and spouses, knocking over tables in the food court as they fled.

“Everybody was trying to get outside,” Johnson said. “When I was coming out, you could see baby strollers turned over, people’s phones and left keys. It was kind of a hectic situation.”

Johnson said he gathered his wife, daughter and son and began heading toward the exit after letting the crowd clear out for a bit.

“My biggest thing was — and not to sound selfish — was to make sure that our family was OK and to get them out safely because this is not something that we love to do for Easter weekend.”

Heavy police presence continued in the area hours after the shooting, though officers began letting more traffic through the streets surrounding the shopping centers and strip malls that are usually packed on weekends. Officers were also stationed outside a nearby hotel designated as a reunification area for people at the scene of the shooting and their families.

Workers from a couple of stores remained clustered in the mostly empty parking lot Saturday evening, waiting for police to let them back inside to retrieve their car keys and personal belongings so they could leave. They said they did not hear or see anything during the shooting but followed the mall’s alert system and were evacuated by police shortly after. They declined to give their names, citing company policies.

“Today’s isolated, senseless act of violence is extremely upsetting and our thoughts are with everyone impacted,” Columbiana Centre said in a statement. “We are grateful for the quick response and continued support of our security team and our partners in law enforcement.”

The shooting is the latest in a rash of shootings at or near malls across the country.

A 15-year-old boy was shot in the head Wednesday outside Brooklyn’s Atlantic Terminal Mall. His injuries were not believed to be life-threatening. Officials said he was with a group of boys when they got into a dispute with a second group.

On Tuesday, a Southern California shoe store owner mistakenly shot a 9-year-old girl while firing at two shoplifters at the Mall of Victor Valley, police said.

And earlier this month, police said six people were killed and 12 others wounded in Sacramento, California, during a gunfight between rival gangs as bars closed in a busy area near the Downtown Commons shopping mall and the state Capitol.
