The BC Coroners Service has confirmed the names of a 51-year-old woman and her toddler grandson who drowned in a tragic accident at a Surrey pool over the weekend.

Investigators believe Warina Nissan, a non-swimmer, jumped into the water after one-year-old Ivan Yousif fell in by accident at an apartment building in the 10500-block of 152nd Street Sunday night.

Both were discovered floating unconscious by a group of children who had kicked a soccer ball onto the pool deck.

The kids pulled them from the water, but paramedics and fire crews who arrived at the scene shortly after were unable to revive the young boy, who was pronounced dead in hospital that evening.

The boy’s grandmother was taken to Royal Columbian Hospital in New Westminster in critical condition, but succumbed to her injuries at around noon Monday.

Their families have been notified.

Police do not believe drugs or alcohol were factors in the accident, and say foul play has been ruled out. The BC Coroners Service is continuing to investigate.

On Monday, two-year-old Kiara Benjatschek was also pulled from a pool in Surrey and taken to BC Children’s Hospital in serious condition. Hospital officials said Tuesday that she is now conscious and in good condition.

The tot and her family were visiting from Calgary when she slipped under the cover on the backyard pool. A family friend managed to pull Kiara free and perform CPR before an ambulance arrived.
