ROUND LAKE BEACH, In poor health. — A 17-year-old boy has died after an accidental fall in his own backyard in Round Lake Beach.

It happened just after midnight Thursday within the 2000 block of Evergreen Lane.

Based on police, the teenager appears to have been climbing a fence within the backyard of his home when he fell.

Residents of the house, in addition to neighbors, heard a loud crash and investigated the incident — then called 911. Police said lifesaving measures were performed on the teenager, but he was pronounced dead shortly after.

Preliminary investigation indicates the boy’s fall was accidental in nature and never suspicious.
