• U.S. marshals join search for sex offender

A registered sex offender that investigators say left Marion County with five juveniles has been added to the state’s Ten Most Wanted list.

Allen Lee Biddix, 18, was convicted as a juvenile in 2002 of first-degree criminal sexual conduct with a minor age 11 or younger, according to the State Law Enforcement Division’s online sex offender registry.

Biddix left Marion County sometime around July 17 with three girls and two boys, said Tim Stec, a spokesman for the U.S. Marshals Service, which has joined the search. The girls are 13, 14 and 15 years old, Stec said. Both boys are 15.

Police think they might have gone to Florida.

Police have issued warrants charging Biddix with contributing to the delinquency of a minor. He also is charged under a federal warrant with unlawful flight to avoid prosecution, Stec said.

• Attorney general investigates Urban League

The president of the Urban League of the Upstate has resigned and the state has begun a preliminary investigation into the organization’s billing for Medicaid services, a spokesman for the state attorney general’s office said Monday.

The inquiry is based on information sent to Attorney General Henry McMaster last month by the state Health and Human Services Department, said McMaster spokesman Mark Plowden.

The inquiry will determine if a full investigation is warranted by the State Law Enforcement Division, Plowden said.

Also Monday, Bill Whitney resigned as president and chief executive of the Upstate office of the Urban League, Randy Romberger, chairman of the organization’s board in Greenville, told The Greenville News on Monday.

• Regulators want further Santee Cooper study

The federal government wants Santee Cooper, South Carolina’s state-owned utility, to conduct further study of the environmental effects of its hydroelectric system as the utility seeks to renew its license.

The Federal Energy Regulatory Commission wants an environmental impact study of Santee Cooper’s 150,000-acre hydroelectric project on lakes Marion and Moultrie.

During earlier hearings, agencies and environmentalists said damming the lakes to provide hydroelectric power has disrupted the environment downstream and hurt fish populations.

The utility has applied for a 30-year renewal of its license to operate the hydroelectric project.
