Prosecutors Kulandra Ratneser and Wayne Caines built their case that Cassidy Ann Salahuddin died from shaken baby syndrome caused by her father Karim Salahuddin through days of medical evidence.

During the trial, the jury heard from doctors and medical experts that the infant was shaken back and forth with extreme force causing severe internal brain and eye injuries.

Key witnesses told the jury that there were no abrasions on the infant's body that would support Salahuddin's story that his daughter rolled down an asphalt hill while inside a pumpkin seat.

The prosecution said Cassidy could not have sustained such severe injuries from a tumble down a hill and doctors told the court that a baby who had fallen about 15 feet down a hill would be bruised, but would not suffer from the extensive injuries found in Cassidy during a post-mortem examination.

Injuries that laid a strong foundation for the defence case included a bruise eight centimetres by eight centimetres on the right of her forehead, bruises to her lip, chest and shoulder and scalp injuries.

Internal injuries included multiple rib fractures, extensive bleeding into the scalp, fractures to the right and left of the skull, torn bridging veins in the brain and “tremendous bleeding in the retina”.

Two overseas medical witnesses were particularly important to the Crown's case.

Dr. Randell Alexander, an expert on shaken baby syndrome from the University of Florida, told the court last week that he believed Cassidy's injuries were indicative of the syndrome.

And American forensic pathologist Dr. Valerie Rao testified during the trial that bleeding around the brain and in the eyes was consistent with trauma caused by being shaken back and forth with extreme force.

The prosecution also relied on statements that Salahuddin gave after the incident on May 5, 2003 in which he stated that he had shaken Cassidy hard enough that her head wobbled around and he slapped her to stop crying.

Although Salahuddin later maintained these statements were false, the jury seemed to take Salahuddin's initial words into consideration - and the fact that he initialled handwritten changes to the statement - when making their decision.
