A Wilton family says an Amazon delivery driver hit and killed their dog and drove off without stopping. Now, they're calling for changes to driver training and protocol.

Erin Higgins and her husband adopted Murphy, a pit bull-bulldog mix, from BARC-CT rescue about one year ago.

“He was this wonky, little, crazy guy. He came from a bad situation, and my husband and I saw a picture of him one day and were like, ‘We have to do it,’” Higgins explained.

She said they promised him a forever home, but an Amazon driver who was delivering a package to their neighbor took that away on Sept. 2.

“Our dogs have an electric fence, and they are allowed to come on part of our driveway,” Higgins told News 12. “The driver dropped the package off, backed up, hit our dog, dragged him, and then just kind of proceeded to drive off—did not stop, didn't knock on our door, didn't call the police.”

Higgins said she rushed the 70-pound dog to the vet with broken bones and terrible road rash.

“The next day after spending thousands of dollars hoping we could save him, unfortunately we could not,” Higgins stated.

The family filed an incident report with Wilton police and immediately reached out to Amazon, which said the company would conduct an internal investigation. This week, they received a settlement for vet costs, but for Higgins, this isn't about money.

“Our message is kind of just like, ‘What's going on? Like how are they training these drivers? What are they doing? How can this happen,’” Higgens said. “We don't even know what ramifications came for this driver. Did he or she go back into training? Are they still on the road?”

Higgins lives on Wakefield Road, a private, narrow road with a handful of homes. She told News 12 that a few years ago, her husband built a custom drop box for mail and packages at the start of the road because of concerns with delivery drivers.

“But they just fly right by it, and they come up the road anyway,” Higgins said.

After Murphy’s death, they put up a sign in front of the box, hoping that will help. It reads, “All delivery drivers, stop. Please leave packages in delivery box. Thank you.”

Higgins and her husband also learned, they're not the only ones in the community with concerns.

“We had about 300-400 people commenting, ‘They do it to us. They almost hit my kid. They've hit my fence,’” Higgins recalled.

Amazon released the following statement: "Safety is a top priority for Amazon, and this includes the safety of pets in the communities we serve. We were deeply saddened by this incident and have conducted a thorough review. All delivery service partners receive comprehensive safety training that includes awareness of surroundings and proper protocols when encountering pets. We continue to work with our delivery service partners to reinforce safe driving practices.”

Higgins told News 12 she decided to share her story in hopes of preventing another family from going through the same pain.

“It's devastating. We treat our dogs like our children,” Higgins explained. “Once a dog comes into our house, they're our family.”
