A father in Michigan is hailing his four-year-old son as his savior after the little boy saved his life. Grant Groenwald was cutting trees near his home last week when a large branch fell on top of him, crushing his leg.

He called out for his son, Quillan, who was nearby. Quillan grabbed a chainsaw and dragged it about 30 feet over to his dad, who then used the chainsaw to free himself.

Today on Shepard Smith Reporting, Shep spoke to father and son. Grant said he would’ve been trapped for hours if his son hadn’t been there.

Watch the adorable interview above.
