What began as a devastating loss for a Kensington man ended in relief and gratitude after a neighbor helped reunite him with his dog’s ashes more than a week after they went missing.

David Frost said he was still grieving the loss of his dog, Luna, when her cremated remains never made it back to his apartment.

“She was like my kid,” Frost said. “I had her almost 17 years.”

Frost, who has rescued dogs for years, said Luna was one of his first. After she was cremated, he expected her ashes to be returned promptly. When days passed without a delivery, he grew concerned.

"We were digging through garbage in case somebody had discarded it," Frost said. "We went through the whole building, knocking on people's doors."

At first, Frost believed the issue was a shipping mix-up. He said the pet memorial company, Pet Haven Lacey Memorial, had accidentally labeled the package for Ocean Avenue instead of Ocean Parkway. But he later learned that wasn’t the problem.

UPS told him the package had been delivered to the correct building on Jan. 23.

“First I actually lose her, and then I don’t have her," Frost said. "It was just nonstop.”

Frost said he checked his building’s lobby, contacted his apartment management and spoke with his doorman, but the package containing Luna’s ashes was nowhere to be found. Desperate for answers, he offered a $250 reward and posted about the missing package on social media.

UPS also told News 12 their system shows the package was delivered at his address.

Just minutes after News 12 arrived to speak with him, Frost received an unexpected message.

A neighbor who lives a few blocks away said he saw Frost’s Facebook post and found the package in his building’s lobby.

“It was really strange,” neighbor Junior Larkin said. “It was just sitting on the windowsill.”

Frost walked over to Larkins building and was reunited with Luna’s ashes.

Larkin declined the reward.

“I have a pet cat, and I would have been devastated,” Larkin said. “It touched my heart.”

Frost said he was overwhelmed by the response from people in the neighborhood who helped spread the word.

“We would have never been able to cover all that ground,” Frost said. “The fact that we could post and the community responded is nice to see.”

UPS said it is still investigating what went wrong.
