It was the sketch that sank Gavin Massey.
The career criminal had been back inside Canberra jail only a week when he received a visit from an associate.
Massey then drew a map, which would lead the man to a loaded double-barrelled shotgun he had hurriedly stashed under some bushes within sight of Parliament House.
But the map was intercepted by the authorities and the police got the weapon first.
Massey, 30, was sentenced to eight years jail in the ACT Supreme Court on Thursday having pleaded guilty to weapon possession and driving a stolen car.
He also asked Acting Justice John Nield to take into account scheduled offences of ammunition and stolen property possession.
The court heard Massey was on parole when he led police on a high-speed car chase in Wanniassa in February 2012.
The stolen vehicle was abandoned but DNA found on a sock on the gear stick and a glove in a footwell linked Massey to the offence.
Massey was involved in a second pursuit in Garran the following month and arrested in Kingston later the same day.
Images of Massey posing near the sawn-off shotgun were found by police on his mobile phone.
But officers had no idea where to find the weapon.
The court heard Massey provided the answer when he sketched the map of Empire Circuit in mid-March last year.
The map was then torn up and tossed in the bin, but a prison guard recovered the drawing and passed it to police.
The entire encounter was also caught on CCTV, with the images tendered in court.
The police managed to win the race to recover the shotgun.
A search of Massey's government flat also uncovered an "Aladdin's Cave" of stolen property, including electronics and jewellery, worth about $20,000.
Justice John Nield jailed Massey for four years and five months.
The court heard Massey was already serving an existing sentence, which when combined with the fresh jail time, totalled eight years and nine months.
The offender will be eligible for parole in May 2016.
"I do not doubt the offender does not regret committing the offences," Justice Nield said in passing sentence.
The judge said Massey's guilty pleas had more to do with the strength of the prosecution case than remorse.
Justice Nield said the offender showed little hope of rehabilitation.
"His past suggests he's not motivated to change his lifestyle.
"I suspect his future will be much like his past. He will surely re-offend when released from prison."
The judge said personal and general deterrence were important factors in sentencing as a reminder repeat offending would not be tolerated and result in "ever increasing terms of imprisonment".
Justice Nield ordered the stolen property not returned to its owners be forfeited to the Crown.
