A pizza shop owner "everybody knew" was working alone when he was allegedly stabbed to death in a random attack outside his business in western Sydney.
Father and husband Sonmez Alagoz, 58, was found on the Great Western Highway, near Kingswood, just after 10pm with a single stab wound to his chest near his Pizza Stop store.
He was just 40 minutes from closing up the shop when seven teenagers as young as 13 allegedly set upon him.

Emergency services treated Alagoz at the scene before he was taken to Westmead Hospital, where he died around 12.30am today.
His nephew Akin Alagoz, said "everybody knew" his uncle.
"He fed Kingswood and Penrith for a long time," he told 9News.
The younger man said he didn't recall driving to Westmead Hospital after the alleged attack.
"It just happened that quickly. We were there and after a while, it sunk in," he said.
The family then returned to the shop to finish the night's work and clean up after the attack.
"We had to come back, finish up what he started last night, finish his last pizzas and kebabs, clean up the shop for him, mop up the blood off the floor," he said.
Homicide detectives investigating under Strike Force Narrira arrested six teenagers – four boys and two girls – from homes in Werrington, South Penrith, and Penrith.
The teenagers in custody and being questioned over the man's death include two girls aged 13 and 16 and three boys, two aged 15, and one aged 17.
A 19-year-old man was also arrested.
A 15-year-old boy was later arrested at St Marys Police Station.

NSW Police Superintendent Trent King said the pizza restaurant owner was well-known in the community and described the incident as a "tragedy".
"It was a confronting scene for emergency responders, he had suffered a gruesome injury and required immediate assistance," King said.
"This gentleman was very closely connected to this community for a very long time, including owning this business for over 14 years.
"This is an absolute tragedy, there's no other way of describing it."
Locals told 9News that Alagoz was a "lovely" and "very kind" man who always greeted his customers with a smile.
"He was really friendly, he treated people how he loved to be treated," one woman said.
"He was a nice, genuine guy."
The grandmother of one of the arrested teenagers said it was a "horrible" situation.
"It's horrible, I feel sorry for the family," she said.
The dead man's family was "distraught", King said.
He said the teenagers were cooperating in custody and police had not ruled out any motives so far.
It is alleged the attack was random.
Police could not confirm if a weapon had been found.
"This is a tragedy that we can't ignore," King added.
A crime scene was established with detectives from Nepean Police Area Command commencing an investigation with the assistance of the State Crime Command's Homicide Squad.
Anyone with information, CCTV or dashcam footage of the area is urged to contact St Marys Police or CrimeStoppers.
