The lengthy trial of a Langley woman accused of killing her seven-year-old daughter is scheduled to start hearing from its final witness on Monday, May 31.

The first degree murder trial of KerryAnn Lewis began last fall, and was expected to wrap up sometime before the end of the year.

However, a combination of delays due to COVID-19 and a pair of late witnesses extended it by almost six months.

Lewis is accused of killing Aaliyah Rosa, who was found dead in Lewis’s Langley apartment on July 22, 2018.

The Crown prosecutors have called witnesses including police officers, the witnesses who found the body, and Aaliyah’s father, Steven Rosa.

The Crown’s case is that Lewis, distraught over her limited access to her daughter, gave the young girl a mixture of over the counter and prescription medication before drowning her in a bathtub.

The defense brought forward a witness who raised questions about Aaliyah’s cause of death.

Dr. Christopher Dunham, a pediatric neuropathologist at B.C. Children’s Hospital, said that his examination of the evidence suggested Aaliyah had a pre-existing condition that could have meant a seemingly minor blow to the head could have caused her death.

In April, Justice Martha Devlin said she will allow one final witness to testify for the Crown as well, Dr. Marc Del Bigio, a neuropathologist and professor at the University of Manitoba. He’ll be testifying as a rebuttal witness about the medical evidence.
