Raleigh, N.C. — America's Most Wanted will feature another segment on the unsolved murder of a pregnant Fuquay-Varina mother found dead behind a Raleigh convenience store.

Jenna Nielsen, 22, died from a single stab wound to the neck in the early morning of June 14 behind the AmeriKing Food Mart at 1709 Lake Wheeler Road.

The seven-minute segment on the deaths of Nielsen and her unborn son, Ethen, will air 9 p.m. Saturday on WRAZ Fox 50.

The TV show featured the case last month and received numerous tips, according to its Web site, that led police to Mississippi to question and to eliminate as a suspect a man who had been in North Carolina at the time of Nielsen's death and resembled a composite sketch of a person of interest in the case.

The person of interest is said to be a male in his late teens or early 20s, standing about 5 feet, 3 inches tall and weighing about 120 pounds. He had black hair pulled into a ponytail and wore a dark-colored sleeveless shirt and baggy denim shorts. Police believe he might be Hispanic.

Anyone with information about the case should call the Raleigh Police Department's tip line at 919-227-6220. They can also report a tip via the NC WANTED tip line at 1-866-43-WANTED or submit it over the Web.

Nielsen's family has set up a Web site, justice4jenna.org, in an effort to keep the case alive and is offering a $10,000 reward for information leading to a conviction in the case.

According to the Web site, the family is also working to design and post a billboard with the composite sketch as another way to help investigators in the case.

"We are just looking for some help keeping our story in the public eye," Nielsen' father, Kevin Blaine, said. "After all, this is not just about our family, it is about the community as well.

"There is still a killer on the loose, and that person needs to be taken off the streets before they can do this to another family."
