A 53-year-old Utah man allegedly murdered his ex-girlfriend, placed her body in a trash bag and stuffed it in a shed near his apartment.

Arthuro Carrion stands accused of murder in the death of Lesa Hyde, who was last seen in Springville around the end of December. The Springville Police Department sent out a press release on Jan. 29 asking for Hyde’s whereabouts and welfare. Cops interviewed Carrion as a “person of interest,” a probable cause arrest affidavit obtained by Law&Crime said. On Sunday afternoon, a witness called Provo police to report a body in a shed behind an apartment complex in the 700 block of Heather Lane.

The caller identified Carrion as the suspect, the affidavit said. Cops found two sheds in the backyard and Carrion in the front yard. When the suspect gave officers the key and they asked him what they would found inside, he allegedly said “a dead body.”

“When the shed was opened the smell of decomposition was plain,” cops wrote in the affidavit. Officers opened several bags, one of which had a “forearm of a human body.”
