A husband and wife celebrating more than five decades of marriage have been killed in a lightning strike outside the White House.

A third victim was pronounced dead on Friday evening, and one other is in hospital with life-threatening injuries.

James Mueller, 76, and Donna Mueller, 75, of Janesville, Wisconsin, died of their injuries after the lightning strike on Thursday in Lafayette Park, located directly outside the White House complex, the Metropolitan Police Department said on Friday.

The third victim was a 29-year-old adult male. The fourth person, a woman, was in critical condition, the police department said. Their identities were not immediately released.

Authorities did not reveal how the people were injured, other than to say they were critically hurt in the lightning strike.

The Muellers were on a trip to Washington DC to celebrate their 56th wedding anniversary, according to their niece, Michelle McNett of Janesville.

"They were a very loving couple," McNett told the Wisconsin State Journal.

"They were very, very family oriented. I think everyone's just in shock right now and kind of request privacy."

The couple had five children, 10 grandchildren and four great-grandchildren, she told the paper.

Officers with the Secret Service and the US Park Police witnessed the lightning strike Thursday night and ran over to render first aid, officials said.

Emergency medical crews were called to the scene just before 7pm and had transported all of the victims to the hospital with "critical, life-threatening injures," fire department spokesman Vito Maggiolo said.

"We are saddened by the tragic loss of life after the lightning strike in Lafayette Park," White House press secretary Karine Jean-Pierre said.

"Our hearts are with the families who lost loved ones, and we are praying for those still fighting for their lives."

Proud Parramatta coach Brad Arthur claims he never doubted his son Jake's ability to brush off trolls and star in his next big opportunity at the Eels.

Arthur enjoyed a big second half in Friday night's 36-20 victory over Manly, setting up two tries in the final 25 minutes after the Eels had trailed 20-14.

The win moved Parramatta closer to the top-four race, with a crucial final month of the regular season ahead for the Eels.

But for the 19-year-old half it also would have meant so much more.

The subject of jeers from so-called Parramatta fans in his last game for the club a fortnight ago, Arthur had easily his best night in the NRL on Friday.

His first assist came from a nicely-placed harbour-bridge ball to Waqa Blake, before he put the game beyond doubt by grubber-kicking for Tom Opacic.

"Regardless of what happened tonight, I know his character and I knew he would handle it," Brad Arthur said.

"I am proud of him regardless. He is my son.

"But that's just his character. He doesn't let things bother him.

"I thought his halves partner did a really good job. He stepped up tonight, which allowed Jake a bit more freedom and a bit more time to get into the game."

The Eels are unsure when they will have Moses back after surgery on his finger, but there is some hope he could return a fortnight before the finals.

Parramatta have South Sydney, Canterbury, Brisbane and Melbourne on the run home, potentially needing to win all four to make the top four.

But in Moses' absence, they showed their attack can still fire.

Arthur aside, Clint Gutherson was brilliant as he set up three first-half tries and scored one of his own after a Shaun Lane offload from within his own end.

Junior Paulo and Reagan Campbell-Gillard continue to be the best front-row pairing in the NRL, completely shifting the match back in the Eels' favour when they returned to the field midway through the second half.

And Dylan Brown was also superb, taking command to dictate play without Moses and also scoring a try of his own late.

"I said to him that it's the best he has stepped up without Mitch there," Arthur said.

"He stepped up as the senior playmaker and let Jake work himself into the game without too much pressure."

Tensions boiled over after two teenagers were jailed for their involvement in the fatal stabbing of 17-year-old Jack Beasley on the Gold Coast.

Supporters of Jack's family clashed with another group in Brisbane Supreme Court after the two boys were sentenced on Friday.

"Your son is a f***ing murderer," a supporter screamed.

Jack's father Brett Beasley said tempers flared after an "absolutely disgusting" comment by the other group.

"One of their family members at the end of it yelled out 'At least our brother is coming home' - who says that?" he told Nine Network.

Security ensured the two groups left the building separately.

Emotions ran high after one boy who was just 15 when he fatally stabbed Jack in 2019 received a 10-year jail sentence and the other - who was 17 - a seven-year term for charges including manslaughter.

The two boys were called cowards by Jack's mother Belinda Beasley in a tear-filled victim impact statement she read in court.

"You have taken away Jack's life and ruined so many others with the choices that you made that night - and for what?" she said.

"You ran away like cowards and left Jack ... to die on the footpath without a care in the world - what sort of people are you?"

The two boys were among five teenagers - aged between 15 and 18 at the time - charged after Jack was killed in December 2019.

Jack was stabbed in the heart and later died in hospital after a fight broke out between his group and the five teens in Surfers Paradise.

Mrs Beasley said her family had endured a "living nightmare" ever since.

She said the sight of Jack's lifeless body at the hospital will "haunt us for the rest of our lives" and the sound of an ambulance siren sparked flashbacks of the night she lost her "beautiful boy".

"We will never be the same. You didn't just kill Jack that day, you killed our entire family - the pain never goes away."

Mrs Beasley said being a juvenile was no excuse for their "unforgivable" actions.

Justice Soraya Ryan said she hoped the boys "carry (Jack's) mother's words with you for the rest of your life".

The boy who stabbed Jack tendered a written apology that was read in court before briefly standing up to say he was "very, very sorry".

"There are no words ... that are going to take away any pain that I have caused," the letter read.

"I understand that I may never be forgiven but I hope one day I will."

Crown prosecutor Todd Fuller said the stabbing "heightened fear" for people going out socialising on the Gold Coast.

Justice Ryan agreed, telling the boys: "Good parents of young people are scared when their children leave home to go out because of people like you".

The younger boy admitted to not only stabbing Jack but also another 17-year-old boy twice during the fight, pleading guilty to murder and two counts of committing malicious acts with intent.

The boy - who is now 17 - must serve 70 per cent of the 10-year sentence.

The other boy - who is now 20 - pleaded guilty to manslaughter and two counts of grievous bodily harm.

On Friday he also pleaded guilty to three other charges including robbery and assault offences that occurred in July 2019 and August 2020.

He must serve 50 per cent of his seven-year term.

He has been in custody for two and a half years - considered time served - and is eligible for parole in 12 months.

Ma-Mal-J Toala - aged 18 at the time - and two teenage boys who can't be named were each found not guilty of manslaughter and two counts of grievous bodily harm after a judge-only Supreme Court trial this year.

Since the tragedy, Jack's family has established a non-profit foundation to curb youth violence.

"Absolutely gutted. How can you put a value of 10 years as a life sentence for taking someone's life," the foundation posted on social media.

The accused gunman who fatally shot three family members on a remote Queensland cattle property has been charged with murder.

The 59-year-old alleged shooter was charged with three counts of murder and another count of attempted murder.

He is expected to appear in the Proserpine Magistrates Court on Monday.

The sole survivor of the shooting is recovering in hospital following the incident between neighbours near Bogie, northwest of Mackay.

Two other people who were being held by police, understood to be family of the man, have been released.

The victims have been identified in media reports as Mervyn and Maree Schwarz, aged 71 and 59, and Maree's son Graham Tighe, aged 35.

Graham's brother Ross Tighe is recovering from a gunshot wound to the stomach, and has been interviewed by police, acting Superintendent Tom Armitt told the Nine Network on Friday.

"What we do know is that the parties involved are neighbours and some conversation has occurred between the parties," he said.

At the 59-year-old's invitation, the neighbours are believed to have met at the boundary line of their properties before the shooting early on Thursday morning.

The injured man managed to flee by car and raise the alarm before being airlifted to Mackay Base Hospital to undergo surgery for critical injuries.

He was found by police some 40 kilometres away from the crime scene, and there was initial confusion about where the shooting took place.

Police locked down the area surrounding the rural cattle properties before conducting a sweep.

"We had a small team of police who drove forward into the crime scene ... not knowing whether the armed offender was present or not, putting their lives in grave danger," Inspector Armitt said.

"Especially when the report was that the people had been shot with a rifle, and they were in danger of being shot from any distance while approaching the crime scene."

The 59-year-old man and two other people were later found on his property.

The small community will be relieved the suspect was in custody, Whitsunday councillor Mike Brunker told the Seven Network on Friday.

"I think these people had only moved over here 12 months ago from out west ... just an absolute tragic situation," he said.

The 59-year-old is a long-term resident of the area.

Queensland Police Minister Mark Ryan said the shooting was particularly confronting given Australia's strong gun laws.

"This is a tragedy on so many levels and obviously there's a police investigation. Hopefully, that investigation is completed soon so that we can provide closure to the family who have lost loved ones," he said on Friday.
