SIX people are dead after Memorial Day weekend sparked an onslaught of violence across America.

At least 56 people were injured in multiple disturbing events over the holiday, including mass shootings and a stampede at a biker rally.

Eleven people were rushed to the hospital on Sunday night when a shooting broke out at a boat dock in a South Carolina beach town.

The shooting started at around 9:30 pm due to an argument during a Memorial Day celebration on a docked charter boat in Little River, which is 30 minutes north of Myrtle Beach, police said.

The worst of the injured are in critical but stable condition, Horry County Police told The U.S. Sun.

In the chaos, an officer responding to the shooting accidentally shot himself in the leg but is now in stable condition.

Cops are still working to identify the shooter who opened fire on the boat.

“As the shooting is believed to be an isolated incident, there is currently no associated risk to the community,” HCP told The U.S. Sun.

BIKE FESTIVAL STAMPEDE

The shooting came hours after a series of fights broke out at a bike rally, sending 12 other people to the hospital less than 10 miles away.

The fighting sparked panic in the crowd early Sunday morning at the Memorial Day Black Pearl Cultural Heritage and Bike Festival in Atlantic Beach, South Carolina, cops told CBS affiliate WBTW.

Cops shut down the celebrations after a stampede broke out when people tried to get away from the violence.

“There were a couple of fights that broke out, causing panic in the crowd and several people were injured trying to leave the area,” Chief Carlos Castillo Jr. told WBTW.

The dozen injured had non-life-threatening injuries.

SHOOTINGS IN CHICAGO

Meanwhile, two people were shot to death in Chicago, Illinois, over the weekend.

Cops haven’t given more information about the two men who were killed in two separate shootings on Saturday.

FAMILY TRAGEDY

A tragedy in Albuquerque, New Mexico, also came to light on Saturday when a 35-year-old lawyer shot his parents and brother to death before setting their home on fire, police said.

Stephen Bockemeier, 76, his wife Marcia Bockemeier, 77, and their adult son Erik Bockemeier, 48, were found dead in their house at 6 am on Saturday when first responders were called to reports of a fire.

While putting out the fire, crews found the murdered family inside with apparent gunshot wounds, according to ABC affiliate KOAT.

Cops later found Stephen and Marcia’s other son, 35-year-old Andrew Bockemeier, after he died by an apparent suicide outside of the State Bar office.

Andrew was a practicing attorney whose license had been suspended in the last year, according to NBC affiliate KOB.

Investigators said Andrew likely shot his parents and older brother based on the gun used in his suicide and a note found with his body.

Albuquerque police didn’t immediately return The U.S. Sun’s request for comment.

More than a dozen other people were hurt in mass shootings that terrorized the country over the holiday weekend.

Seven people, including children, were injured in a shooting at a park in Jackson, Tennessee, on Saturday night.

One of the gunshot victims was rushed to the hospital in critical condition, two were in stable condition, and four others were released from the hospital, cops said on Sunday morning.

That same night, six people were shot in what cops called an “active shooter” situation that stemmed from an argument in Colorado Springs, Colorado, according to Fox affiliate KDVR.

A woman who lives near the crime scene told the outlet she saw the awful aftermath of the shooting.

“When I came outside, people were still laying on the ground,” Kendre Thunstrom told KDVR.

“It was terrible. Bodies everywhere, people were groaning, moaning.”

HORROR DOWNTOWN

Four people were also injured in a shooting in downtown Savannah, Georgia, early on Saturday morning.

Street footage showed the terrifying moment when barhoppers ducked and ran for cover after shots were fired at around 2 am.

Savannah Mayor Van Johnson said the gunfire, sparked by an altercation between two groups, was “senseless and unnecessary.

“We must do better. Violence is not the answer,” Johnson said.

“I urge everyone: resolve your disputes with respect and maturity—because your life and someone else’s may depend on it.”
