Investigators in Montezuma County, Colorado, have found dismembered body parts in concrete buckets at a missing man’s home, and arrested the man’s son on suspicion of murder, the sheriff said Tuesday, according to the Associated Press.

Jack Berry’s relatives said he had been missing for several months, but investigators have not yet determined whether the dismembered body was Berry’s.  Jeremiah Raymond Berry, 20, is currently being held on a $500,000 bond until the investigation finishes.

Sheriff Gerald Wallace said the body parts were found in the buckets following a CT scan done at a hospital. The scan revealed body parts inside.

"It's not like your normal homicide where you have a body lying there, and you can identify him," he said. "There were some body parts in two buckets of concrete."

As parts of the body are still missing, investigators are using a dog trained to find cadavers, in order to discover the rest of them.

One of the buckets was found at Berry’s home, but police did not reveal where the other buckets were found.

The investigation began Monday after the Arizona Department of Public Safety relayed a missing person report about Jack Berry to Colorado officials. The person who originated the report has not been identified yet.

Jeremiah Berry was considered the first person of interest. According to the Associated Press, the sheriff declared he helped investigators with the search.
