Federal agents and NYPD officers descended on a building in lower Manhattan Thursday morning in a new search for evidence in the case of a 6-year-old boy missing for more than 30 years.

The property is on Prince Street in SoHo, the same street where Etan Patz was last seen on May 25, 1979. An NYPD spokesman told CNN that authorities are looking for “human remains, clothing or other personal effects.” The search effort is focused on the basement, a currently-unoccupied 13’ x 62’ space with a cement floor.

CNN’s Susan Candiotti reported that FBI evidence recovery teams plan to use jackhammers to dig through the floor and they expect to continue the search there for five days. Candiotti told HLN’s Nancy Grace investigators believe Patz may have been killed or disposed of in that basement.
Patz vanished after leaving his family’s Prince Street home to walk to his school bus stop two blocks away. His disappearance spurred a nationwide search and the development of new ways to look for missing children, including posting their pictures on milk cartons.

A man who has been identified as a suspect in the case, Jose Antonio Ramos, is in prison in Pennsylvania for unrelated child molestation charges. A Department of Corrections spokeswoman confirmed to HLN Thursday that Ramos is scheduled to be released on November 7, 2012.

Police And Volunteers Search For Missing Ohio Woman On Her Birthday August 17, 2011 On her 22nd birthday and the first anniversary of her engagement, more than 100 people joined a search for a missing Ohio woman Tuesday.

Katelyn Markham was last seen at her Fairfield home by her fiancé late Saturday night. John Carter told the Middletown Journal that he left her townhouse around 11:30 pm that night and received a picture from her via text message at 12:52 am Sunday. She did not respond to texts he sent the following morning and did not show up for work at a bridal shop in a nearby mall.

Carter told the newspaper that he was concerned when he could not reach her, so he went to her townhouse looking for her and found her car there. Her purse and her keys were inside her home and her dog had been locked in her bedroom. However, her cell phone was gone.

Nobody has heard from Markham since the picture she sent Carter early Sunday. According to information posted by the Ohio Attorney General's Office, Markham's cell phone and its GPS tracking device were turned off around 12:45 am Sunday.

Police have reportedly found no evidence of foul play at this point, but they are considering all possible explanations for Markham's disappearance.

Carter told the Cincinnati Enquirer that Markham was planning to graduate from the Art Institute of Ohio-Cincinnati this fall and that the couple had discussed moving to Colorado after that. He said she seemed excited about their future.

Friends agreed that it would be out of character for Markham to leave without telling anyone. Still, after three days with no sign of her, Carter has not lost hope.

"I just feel and know in my heart that she's alive and we're just doing what we can to bring her home," he said to Local 12.

Katelyn Markham is described as 5'4", 130 lbs. with green eyes and brown hair.

Anyone with information about Markham's whereabouts can contact the Fairfield Police Department at 513-639-7820.
