Testimony at the trial for a Calgary mother who treated her ill son with homeopathic remedies continues and on Tuesday court heard that the seven-year-old boy died from ‘overwhelming sepsis.’

Ryan Lovett died in March 2013 after contracting an infection that left him bed ridden for 10 days.

His mother, Tamara Lovett, 47, was charged with failing to provide the necessaries of life and criminal negligence in the boy’s death and her lawyer entered a not guilty plea on Monday.

On Tuesday, the ER doctor who assessed the boy told the court that anytime a child arrives without sign of life there is a low probability that they will revive him.

Dr. Jennifer D’Mello testified that Ryan was already dead when he reached Alberta Children’s Hospital on March 2.

"He certainly was already dead at the time he arrived in the emergency department and was cold to the touch," she said. "I thought it was very unlikely that we would be able to revive him from the time that he arrived. Any time that a child is arriving without any signs of life is a real low probability that we will revive them."

The acting chief medical examiner, Dr. Elizabeth Brooks-Lim, also took the stand and told the court that an autopsy was done on the young boy because his death was unexpected and unexplained.

Dr. Brooks said the boy’s body was full of Group A streptococcus, which had caused most of his major organs to deteriorate.

"It was the result of multi-organ failure. Every organ in the body was starting to fail. This child died because of an overwhelming sepsis and parainfluenza," said Dr. Elizabeth Brooks-Lim.
 
"The major organs all showed signs of an infection of the blood...that is to say sepsis or septicemia and as a result of this infection the organs that normally produce the immune response of the body appeared exhausted from having to counter an infection."

She said that there were signs that his body tried to rid itself of the infection but that his immune system was too exhausted.

Brooks also said that Ryan’s body appeared normal and there were no signs of abuse.

Ryan's father, Brian Jerome, says he last saw his son when he was three-years-old and that he found out about Ryan's death on social media.

"Devastating, I literally hit the floor and I haven't been able to recover ever since. I'm shaking, it's mind blowing," he said. "It was just a fluke that I seen on Facebook all these condolences and stuff but I didn't know what happened. I contacted some of her friends and they told me what happened."

The trial is being heard by a judge and is expected to last about two weeks.
