A 26-YEAR-OLD woman who glassed a man with a mason jar during new-year celebrations in 2014 has been sent to jail.

Keren Alana Sives-Hill pleaded guilty to one count of wounding when she appeared in Warwick District Court on Thursday.

Both Sives-Hill and the victim were at Washpool Camping Reserve, at Leslie Dam, on December 31, 2014.

Sives-Hill and the victim were celebrating New Years at different campsite but the two parties soon crossed paths.

Sives-Hill met a man she had gone to school with and joined his celebrations. Just after midnight the pair made their way to the victim’s site and tried to join in.

The victim pushed away the man multiple times, before feeling a blow to the left side of his face, which was caused by Sives-Hill smashing the glass into the man’s face. The jar shattered on impact.

The victim grabbed at his face and fell to the ground.

A witness told police Sives-Hill said immediately after the incident “I’d better get out of here”.

She fled the scene, while the victim clung to his face.

The court heard at one point he could not see, and lost and regained consciousness.

He sustained a deep 20cm gash to his face.

Crown prosecutor Shauna Rankine told the court before the attack Sives-Hill was seen to be “slurring words” and “unsteady on her feet”.

Sives-Hill’s lawyer Robbie Davies told the court the glassing was a spontaneous reaction to seeing her friend being pushed backwards.

“She just reacted and it obviously had dreadful consequences,” he said.

Judge David Andrews acknowledged Sives-Hill had been drinking excessively the night of the glassing.

“You struck him when you were coming from behind and outside his field of vision,” Mr Andrews said.

“I do accept that, so far as you were concerned, the complainant had pushed several times a young man with whom you felt some alliance on that occasion.

“So there is some explanation why you would have become infuriated with the complainant, sufficiently to lose control like you did.

“I’ll sentence you as if it was less serious than the photographs suggest. It was a significant injury, nevertheless.”

She was sentenced to 18 months jail, to serve a minimum of four months.
