Was he released early?

The Herald reports:

Nikki Roper strangled his ex-girlfriend Alexis Tovizi to death with a sleeper hold just days after being released from prison where he was serving a sentence for choking her, a court heard today.

The trial is ongoing so whether or not Roper is guilty is for the jury. So please don’t comment on him or his possible guilt or innocence.

I’m interested in whether or not he was released after his full sentence, or on parole? Anyone know?
