SPRING VALLEY, N.Y. — Police say a New York mother who couldn’t handle her 4-year-old son tied him to a bush while she went into an apartment to baby-sit.

Spring Valley Police Chief Paul Modica says 22-year-old Mery Isabel Quinde-Castro left her son outside for more than 30 minutes Tuesday. She was charged with endangering the welfare of a child and released on $2,500 bail.

Modica says a neighbor called police after spotting the boy tied to a bush by a tether on his backpack.

Quinde-Castro didn’t answer reporters’ questions about the charges. But her sister, Rosa Quinde-Castro, says she did nothing wrong and is a “good mother.”

The boy was turned over to a relative.
