'I watched life leave his eyes': Parents warn against metal straws after 4-year-old is stabbed in the throat

It was a beautiful June day on Long Island, and Crystal DeFraia was waiting for a technician to service her family's new in-ground pool, which she envisioned would be at the center of a fun-filled summer break. 

Before he arrived, she offered snacks to her daughter, Madison, 8, and her son, Charlie, 4. The boy picked his favorite drinkable yogurt, which he enjoyed slurping through a metal straw.

She was in the backyard chatting about the pool when she heard her daughter scream. Madison appeared, a look of horror on her face. 

Charlie, she said – he fell off the porch.

Crystal ran to find her son covered with blood. At first, she thought Charlie had broken his nose or bitten his lip, but there was too much blood.
