A medical examiner who examined the body of the shooting victim, Josue Silva, concluded that the Western University student died after being shot in the abdomen and losing an excessive amount of blood despite the efforts of paramedics to save him.

In a London court on Tuesday, Dr Ted Tweedie told the jury: “He died from hypovolemic shock, he bled to death.”

He said Silva suffered a gunshot wound and the wound had soot around it.

The 18-year-old had been at a bush party near Pack Road, south-west London, with dozens of other youths when the shooting happened on July 30, 2021.

Dr Tweedie testified that Silva also had some superficial abrasions on his body.

After the blood was taken, the doctor concluded that Silva “had a relatively low concentration of alcohol and no other substances were found.”

In the days after the shooting, Emily Altmann and Carlos Guerra Guerra were arrested and charged. Both have pleaded not guilty to second-degree murder and assault causing bodily harm.

The jury heard that Altmann was at the bush party all night and that Guerra Guerra arrived later in the evening.

Dr. Tweedie’s trial and testimony resumes on Wednesday.
