A missing 24-year-old soldier from Fort Bragg whose apartment was found burned this week had sought court protection from an Illinois woman who allegedly tried to "embarrass" her and her husband online, FOX News has learned.

The soldier, 2nd Lt. Holley Wimunc of Lafayette, La., was granted a "no contact" order last year against Lindsay Hunter of Avon, Ill., by a North Carolina judge.

Wimunc wrote in court documents that Hunter repeatedly had posted photographs of herself and Wimunc's Marine husband, John Patrick Wimunc, on the Internet with comments, and that Hunter had been harassing the couple.

It wasn't clear how Hunter and the Wimuncs knew each other, if at all. A Raleigh TV station reported that it had reached Hunter by phone, but she had declined to comment.

Holley Wimunc, assigned to Fort Bragg's Charlie Company at Womack, also filed court papers about two months ago alleging domestic violence on the part of her husband, whom she was divorcing at the time of her disappearance.

Wimunc's complaint resulted in a temporary restraining order against her 23-year-old husband.

John Wimunc had gotten drunk, held a loaded handgun to her head and his head, choked her and threatened to kill himself and her, Holley Wimunc wrote in the complaint.

Police have interviewed John Wimunc, but he has not been named as a suspect in his wife's disappearance.

Col. Terry Walters, Wimunc's commander, said in a statement Friday that staff at Womack Army Medical Center, where Wimunc worked, was "very concerned about her safety."

Officials responded to a call about the strong odor of gasoline at the Morganton Place Apartments in Fayetteville and found a smoldering fire that had burned two bedrooms. Police are calling it an arson and missing person's investigation.

Wimunc's car was still in the parking lot when police arrived. The Fayetteville Observer said police towed the car to examine it.

"Right now we're still processing a crime scene of arson where she lived at," said Fayetteville Police Department Lt. David Sportsman. "Yesterday we were contacting family and friends to see if anybody knew where she was at before we released the information today. We wanted to make sure she wasn't somewhere else."

Wimunc arrived at Fort Bragg in August 2007, base officials said.

Also Friday, authorities said a second autopsy of a pregnant Fort Bragg soldier found dead in a Fayetteville motel June 21 confirms she was the victim of a homicide. Army Spc. Megan Touma, 23, of Cold Spring, Ky., was found June 21 in the bathroom of a motel room after a maintenance supervisory smelled a four odor coming from her room. The cause of her death hasn't been released.

The Armed Forces Institute of Pathology conducted the second autopsy at the request of Fayetteville police and military investigations.
