He was found with fatal stab wounds by another service station worker preparing to start their shift.
A 29-year-old Caltex service station attendant was stabbed to death shortly before midnight on Thursday - one of five violent incidents police believe are connected.
It finished around 6.35am on Friday with the arrest of two teenagers, aged 15 and 16, on the Monaro Highway south of Isabella Drive.
He had a current AVO out against him in Young Local Court to protect a female and is awaiting trial in a District Court on aggravated sexual assault to inflict actual bodily harm with a weapon.
Members of the public are urged not to approach the teens if they locate them, but to contact Triple zero (000) immediately.
Ms Burn said another line of inquiry was whether the incident was drug related.
However, just before 1am, emergency services responded to reports of a stabbing on Cook St, Turrella - just around the corner - where they found a 25-year-old woman with multiple stab wounds to her arms, face, neck and shoulders.

The teenagers were taken to the ACT watch house after their arrest, with NSW Police seeking to extradite them to NSW.
"It doesn't get more serious than this", Superintendent Rod Smith told reporters this morning.
The police are now requesting their extradition back to NSW.

The offenders had become locked inside the store and allegedly smashed their way out a window to escape. "It's an absolutely horrific series of events".
"We'd just like to reassure everybody that there are two people that we believe are involved and both of those people are now in custody", he said.
Police will allege the two boys walked into the Caltex store at 11.45pm and began fighting with the attendant.
There were several other violent incidents between the two stabbings that the pair may be involved in, police say.
Queanbeyan residents quickly took to social media to share their distress at the news of the service station employee's death.
