ONE YEAR LATER: Father of missing Hoggle children not giving up hope in finding them

It has been one year since two little children disappeared in Montgomery County while in their mother's care. Prosecutors do not believe the kids are alive, but their father told FOX 5 there is just nothing to prove that.

"You're going to have to show me some type of hard evidence for me to not believe that they're out there," said Troy Turner, the children's father.

Jacob Hoggle, who was two years old at the time, disappeared on September 7, 2014. His mother, Catherine, had left with him, but returned alone giving family members various excuses. The next morning, she did the same with 3-year-old Sarah.

Catherine Hoggle then vanished herself for several days. She was eventually found wandering the streets in Germantown and taken into custody.

Hoggle remains in a psychiatric hospital facing charges including child neglect. She has been diagnosed with paranoid schizophrenia and is awaiting a fourth competency hearing.

Hoggle maintains that her children are safe. She says she dropped them off with someone, but refuses to give any details. Her lawyer refuses to allow police to interrogate her citing Fifth Amendment rights.

Turner told FOX 5, "It seems to me she has more rights in that place, whether it's HIPAA or the rights of someone on trial, than my kids do to be found."

Hoggle's defense attorney David Felsen said, "I don't know that Catherine knows what happened."

He continued, "I don't know that she could relay it if she knew."

Hoggle is due back in court on September 18. If she is eventually found competent to stand trial, the Montgomery County State's Attorney's Office would have to decide whether to pursue a "no bodies" homicide case.

Anyone with information about Sarah and Jacob Hoggle's whereabouts is asked to call Montgomery County Police immediately at 301-279-8000. Callers may remain anonymous.
