A federal judge ordered a former interim Delaware County sheriff to remain incarcerated while awaiting trial after his arrest on a child-pornography charge last week.

Mark W. Wolfe surrendered to authorities Monday, Aug. 10, after he was charged with receipt and distribution of child pornography. Investigators with the FBI's Child Exploitation Task Force discovered hundreds of pornographic videos and images featuring children after executing a search warrant July 31 at Wolfe's Kingston Township residence, according to a criminal complaint filed in U.S. District Court in Columbus.

U.S. District Court Magistrate Judge Norah McCann King ruled at a hearing Thursday, Aug. 13, there is "probably cause to believe the defendant has committed an offense for which a maximum prison term of 10 years or more is prescribed," according to court records. The detention order also states: "There is a serious risk that the defendant will endanger the safety of another person or the community" if released.

The judge committed Wolfe to the custody of federal authorities pending his trial.

Wolfe, 50, listed as the founder and president of ARES Security and Consulting on the firm's website, served as interim sheriff of Delaware County for five days in 2007 after Sheriff Al Myers resigned.

Wolfe was a sheriff's deputy in Delaware County from August 1994 to September 1997. He also previously served as chief of police in Scioto Township and Edison, Ohio.

According to the complaint, investigators determined in June an IP address registered to Wolfe's home address was used to download multiple pornographic videos involving children through a public peer-to-peer file-sharing program.

A preliminary investigation of a laptop computer seized in the July 31 search of Wolfe's home found 486 videos and 203 images of child pornography, the complaint states.

The complaint also states someone who identified himself as Mark Wolfe discussed his sexual interest in children multiple times during online conversations recovered from the computer.

Officers with the Powell, Reynoldsburg and Westerville police departments collaborated with the FBI and the Offices of the U.S. Attorneys on the investigation.

During Wolfe's brief stint as sheriff, the sheriff's office put out a news release accusing Myers of possessing child pornography on a county-owned computer. State investigators later cleared Myers after concluding the material was legitimately stored as part of an investigation.

Delaware County later reached a settlement in 2010 with Myers in a defamation lawsuit over the inaccurate news release.

Court records show Wolfe waived his right to a preliminary hearing Aug. 13. No future court appearances were scheduled as of Friday, Aug. 14.
