WASHINGTON — The brutal roadside rape case of a woman in Stafford County has caught the attention of two members of Congress, who want more information about the man charged with the crime.

Rep. Bob Goodlatte, R-Va., and Sen. Chuck Grassley, R-Iowa, sent a letter to Homeland Security Secretary Jeh Johnson this week, requesting the criminal and immigration histories of Roberto Carlos Flores Sibrian, who is reportedly in the United States illegally.

Sibrian, 26, was arrested Nov. 10 in North Carolina, where he is being held on $100,000 bond. He was charged with rape and aggravated sexual battery, according to a statement released by the Stafford County Sheriff’s Office Nov. 11.

Authorities suspected Sibrian of driving the dark-colored SUV that struck a woman’s vehicle on State Route 3 in the early-morning hours of Oct. 31. After the crash, the woman was dragged to a nearby ditch, where she was sexually assaulted by the driver of the striking vehicle for two hours, investigators said.

The Stafford County Sheriff’s Office said Sibrian was in the country illegally, had no fixed address and had been staying in the Fredericksburg area before the alleged sexual assault.

In their letter to Johnson, Goodlatte and Grassley requested details of how and when Sibrian entered the U.S., if he had been deported in the past, and whether he had any gang affiliation.

In a news release, Goodlatte and Grassley asked “whether Sibrian would have been considered an enforcement priority under the Obama Administration’s Priority Enforcement Program, prior to the rape charges,” and “whether federal officials have contacted the victims of the alleged crimes committed by Sibrian.”
