A Brisbane woman who was run over by her own car as it was allegedly stolen by a group of teens has told of her disappointment after charges were dropped against one of them due to a lack of evidence.

Emma Trillo and her partner were woken by a disturbance at their home in Ascot about 4.30am on September 10 last year, before Trillo was run down by her own black BMW and left with a fractured hip, pelvis and spine.

Leo Angelo Matar, 18, has today had all charges against him relating to the alleged confrontation dropped.

At a previous bail hearing, the court heard the prosecution's case heavily relied on a thumbnail-sized photo that allegedly showed Matar with two teens taken on the day of the alleged crimes.

Those two 16-year-olds are still facing charges over the incident.

"The system has really let us down in this scenario," Trillo said.

"My bones have healed, but soft tissue injuries are still in play. I'm still seeing physio.

"Still to this day, we have trouble sleeping of an evening."

Matar's father David Sandford, said the family was relieved.

"We just want to get him recovered. We just wanna get him back on the track," he said.
