COLORADO SPRINGS: A Colorado funeral home owner who stashed 189 decomposing bodies in a building over four years and gave grieving families fake ashes was sentenced to 40 years in state prison on Friday.

During the sentencing hearing, family members told Judge Eric Bentley they have had recurring nightmares about decomposing flesh and maggots since learning what happened to their loved ones.

They called defendant Jon Hallford a “monster” and urged the judge to give him the maximum sentence of 50 years.

Bentley told Hallford he caused “unspeakable and incomprehensible” harm. “It is my personal belief that every one of us, every human being, is basically good at the core, but we live in a world that tests that belief every day, and Mr. Hallford your crimes are testing that belief,” Bentley said.

Hallford apologized before his sentencing and said he would regret his actions for the rest of his life. “I had so many chances to put a stop to everything and walk away, but I did not,” he said. “My mistakes will echo for a generation. Everything I did was wrong.”

Hallford’s attorney unsuccessfully sought a 30 year sentence, arguing that it was not a crime of violence and he had no prior criminal record.

His former wife, Carie Hallford, who co-owned the Return to Nature Funeral Home, is due to be sentenced April 24. She faces 25 to 35 years in prison.

Both pleaded guilty in December to nearly 200 counts of corpse abuse under an agreement with prosecutors.

During the years they were stashing bodies, the Hallfords spent lavishly. That included purchasing a GMC Yukon and an Infiniti worth over $120,000 combined, along with $31,000 in cryptocurrency, pricey goods from stores like Gucci and Tiffany & Co. and laser body sculpting.
