Dylan Skalina, a 12-year-old boy, had just finished trick-or-treating with his friends when he collapsed on Halloween night after suffering a brain aneurysm. He died the next day at a Phoenix hospital and is expected to help more than 300 people through his organ and tissue donations.

Scott Sorry, also known as Gerard Scott, lost a battle with brain cancer and died on Thursday — which was also his 47th birthday. His family posted on his Instagram account announcing his death.

While trick-or-treating with friends, Dylan Skalina suffered an aneurysm and later died. Because he is an organ donor, however, he could save more than 300 lives.
