It was a literal nightmare on Elm Street for a Texas woman who got quite the pre-Halloween scare when workers renovating her backyard this month found an old rusted coffin with bones still inside.

Deedee Oliveira, who recently bought the house on Elm Street in Mission, told KGBT she was shocked when the casket was unearthed.

“I’m like, ‘A coffin? What do you mean a coffin?” Oliveira said. “I can’t even explain it, it was huge. It had the handles. It was really rusted, and it had bags wrapped around it.”

“They had seen little booties and pink little bears and then one of the guys said that he had seen bones"

Oliveira received a call on Tuesday from workers after they hit a hard object in the ground.

“They called, and they let my dad know first that they found a box,” Oliveira said. “And so my dad said, ‘Okay, we’ll move the box later so you can finish.’”

When the workers used an excavator to lift the object from the dirt, Oliveira said she couldn’t believe a casket was hanging from the metal chain attached to the claw of the construction machine.

“They had seen little booties and pink little bears and then one of the guys said that he had seen bones,” Oliveira said.

The bones, it turned out, belonged to the previous owner’s beloved cocker spaniel. And they weren’t alone in the makeshift cemetery: workers later dug up cat bones inside a tool box buried near the coffin.

“Thank God it was a dog and not human remains,” Oliveira said. “If not, I think I would’ve gone crazy.”
