A man has been charged over the fatal stabbing of a 17-year-old male in a quiet country town just one month after another teen was also killed in a knife attack.
Emergency services were called to a home on McDougall Street in the NSW Northern Rivers town of Casino early Saturday morning.
The teen was found with stab wounds to his neck but died at the scene, despite desperate attempts to revive him.
The boy's parents were home at the time of the brutal attack.
Detectives cordoned off the street and launched Strike Force Linford to investigate the death believed to be linked to another fatal stabbing outside a KFC on May 29.
Strike force inquiries led to the arrest of a man, 18, at a buy wine casino home on Sunday morning.
A teenage boy was allegedly stabbed to death at his Casino home on Saturday morning
He was charged with murder and refused bail to appear in Lismore Local Court on Monday.
A second crime scene was established at his home after the man's arrest and is being forensically examined.
The victim's home has also been forensically examined by dozens of police.
'They're quite distressed as you would be, losing a child in any circumstances is tragic enough,' Superintendent Scott Tanner said.
Additional officers from the region and homicide detectives from Sydney have been deployed to assist with the ongoing investigation.
Police believe the alleged incident was a 'targeted' attack linked to last month's mass brawl.
Police launched a strike force to investigate the teen's death and made an arrest on Sunday morning.

Lachlan Andrews, 17, was fatally stabbed in NSW's Northern Rivers region last month
Lachlan Andrews, 17, and Harrison Hone, 18, were allegedly stabbed outside the fast-food restaurant when a fight involving 20 people broke out around 5.10pm on May 29.
Mr Andrews died at the scene while Mr Hone was rushed to hospital in a serious condition before later stabilising.
Police are probing if Mr Andrews was targeted over a love triangle involving his pregnant girlfriend.
Locals have been left shellshocked by the string of violence.
'It's scary and it's very sad,' one neighbour told Nine News.
'Quiet people.
Loveliest people you'd ever meet.'
Another added: 'I just don't get it why teens these days can do things like that. There's no need for it.'
The latest alleged stabbing comes four weeks after Lachlan's death on May 29, described by devastated loved ones as a 'caring family man'
A 17-year-old boy was later charged with murder, reckless wounding and affray.
