Eight-year-old Caleb Whitman was running late for school again. His sneakers slapped the pavement as he cut across the Riverside Plaza parking lot, hoping to shave off a few minutes. His teacher, Mr. Lawson, had warned him the day before that another tardy slip meant a call home, and Caleb dreaded disappointing his parents once more.

But halfway across the lot, something made him stop short. In a dark blue hatchback, parked directly under the sun, a small baby sat strapped in a car seat. The child’s cheeks were crimson, his mouth opening and closing in desperate cries that barely carried through the sealed glass. Droplets of sweat clung to his temples.

Caleb pressed his face to the window, knocking with his knuckles. No adult appeared. He tugged at the handles on each door, one after another, but every lock held firm. His pulse quickened as the infant’s wails weakened into short, raspy sounds.

The plaza was strangely quiet. A few shopping carts rolled in the breeze, but no shoppers were near. School was just three blocks away, yet the thought of abandoning the baby gnawed at Caleb’s stomach. He understood enough to know that waiting could be fatal.
