AceShowbiz - Jenelle Evans and her husband David Eason didn't seem to be bothered by the reported investigation on them after her son Jace ran away three times in less than two months. The couple was seen attending a gun show alongside their kids on Sunday, October 15.

In pictures obtained by TMZ, the former "Teen Mom" star and her husband had a family outing at a gun event in Wilmington, NC. At the show, firearms, knives and other weapons were displayed on tables for gun enthusiasts.

According to an eyewitness, Jenelle and David brought her 9-year-old son Kaiser and their 6-year-old daughter Ensley. Jenelle's oldest son Jace, meanwhile, was not in sight during the outing.

David and Kaiser allegedly hung out together as they checked out several weapons, including knives, holsters and rifle scopes. Eventually, David decided to buy a bullet-proof vest for himself as well as a wooden battle ax for Kaiser. The family reportedly didn't stay at the event for too long as they left after 20 minutes.

The family's eyebrow-raising choice for their weekend outing came after it was reported that Jenelle and David could face charges of assault and neglect after Jace's multiple attempts to run away. TMZ claimed that an investigation into the family is due to wrap up soon after law enforcement interviewed the 14-year-old, whom Jenelle shares with her ex Andrew Lewis.

After running away, Jace allegedly told the authorities that his stepdad David had assaulted him and the police had a video showing David assaulting Jace. It was also said that Jace sported visible marks on his neck and arm. Jace was later released to his grandmother after spending over a week in a North Carolina hospital.

Earlier this year, Jenelle regained custody of Jace from her mom Barbara. Months later, the MTV star reported him as missing in the area of her North Carolina home. Thankfully, he was confirmed safe later though he made two other runaway attempts in less than two months.
