LAS CRUCES, N.M. — A horseback rider made a gruesome discovery Sunday in Las Cruces. He stumbled upon some human remains. According to police, the rider made the discovery near West Picacho, just east of the rest stop on US 70. Most of the remains were bones. They are now being sent to a state lab in Albuquerque. Meanwhile, authorities this week will continue combing the area looking for more clues such as clothes, jewelry, or other bones. Police don't know who the remains belong to and say it's too early to speculate whether foul play was involved.
