Two 14-year-old boys pulled from a Scarborough swimming pool with no vital signs last week have died.<p/>The drowning occurred at a condo at 30 Thunder Grove near Finch Avenue and McCowan Road just before 4 p.m. June 30. <p/>Police said the teens were visiting a friend in the building and that the friend let the boys into the indoor pool. <p/>"They jumped into the deep end," said Det. Dawn Rose of 42 Division. "The friend went and got the security guard. The security guard called 911."<p/>The first police officer on scene and a firefighter dove into the pool and pulled the teens out. <p/>The boys were taken to The Scarborough Hospital's Birchmount site where one died. The other was transferred to the Hospital for Sick Children via an emergency run. He died on Friday.<p/>No names have been released.<p/>"It's a very tragic accident," Rose said. <p/>"Police and EMS did everything they could to save these two boys."<p/>The pool at 30 Thunder Grove has no lifeguard. A sign posted on a wall says: "Caution this pool is unsupervised. Bathers under 12 years of age are not allowed within the pool enclosure unless accompanied by a parent or his agent who is not less than 16 years of age."<p/>Rose said police have surveillance video from the pool.<p/>"Given the warm weather...children are going to be using the pools more and more often," she said. "People need to take appropriate safety precautions. Parents need to make sure that their children are well supervised."
