From USPS News Link:
Blackwood, NJ, Carrier Technician Lonna Lenher was recently making deliveries when she grew concerned about an older customer whose mail was piling up.
Lenher knocked on the woman’s door and got no answer, so she alerted a neighbor, and police were asked to check on the customer.
Officers soon discovered that the woman was stranded on her bathroom floor after suffering a stroke two days earlier, and paramedics were dispatched to the scene to rush her to a hospital.
Other neighbors on the route later visited the local Post Office to commend Lenher for her critical intervention.
