While searching for Susan Powell, who went missing two years ago in Utah’s desert, authorities found unidentified human remains on Wednesday. The unidentified remains could result in a major break in the cold case.

Authorities were not sure whether the remains belonged to Powell and forensic experts were on the way to the scene. The main focus of investigation is Powell's husband, but he has never been charged or arrested.

It's a game of patience at this point, West Valley City Sgt. Mike Powell told the Associated Press. We need to slow down a little bit and identify what it is we found.

Powell said authorities sealed off the area on Wednesday evening and would resume their search in the morning.

Powell, then 28, was reported missing on Dec. 7, 2009. She was last seen at a church by her friends. She also failed to show up for her stockbroker job.

Her husband, Josh Powell, told police that he left his wife at home around 12:30 a.m. that day to go winter camping with their young sons -- then 4 and 2 -- on the Pony Express Trail, which is about 80 miles west of Salt Lake City, AP reported.

Though her husband is the only person of interest in the case, Susan’s family believed that she ran off with another man. Authorities have been combing the area near Topaz Mountain in Juab County since Monday. The site is about 135 miles southwest of the location where Powell was last seen in West Valley City, according to The AP.

It added that Susan's father, Chuck Cox, and his family remain hopeful, but were preparing for the worst.

Josh Powell’s family claims that Susan was sexually immoral and emotionally unbalanced.
