DESOTO COUNTY, MS -- It's been almost a week without a deadly shooting on Mississippi highways. Law enforcement in multiple counties are patrolling in force, investigating the theory the shooter could be posing as a cop.
The second victim, a casino employee, was killed early last Friday morning, driving home from work in Tunica. ABC 24 News has learned Tunica's casinos started warning employees to take extra precautions as soon as it happened.
Tourism and casino reps say business hasn't dropped off in Tunica since the shootings, but just like law enforcement, casinos are warning both their employees and patrons to be cautious, not to press their luck.
"I get off and come straight home and say a prayer," says Jennifer Young. A prayer she'll make it home safe. As a casino employee, Young has been on edge since the two deadly highway killings.
"That's my job I have to go to. My hours are crazy because it's the casino business. I get off at 3 in the morning."
Fresh in her mind, that's an hour after Lori Carswell, a woman who also worked nights at a Tunica casino, was shot and killed last Friday.
Cops are urging drivers to call 911 if they see anything that makes them uncomfortable.
"I've gotten to where I keep my cell phone in my hand and if anyone comes around me I flip it like I'm talking on it," Young says.
"She's 35 and I'm still waiting up at night for her to get home because I want to make sure she's there," says her mother Laura Oliva.
Tunica is one of several Mississippi counties keeping a watchful eye. Investigators can't say who the shooter is targeting or why.
"Our counties are safe. A safe place to live, shop and come enjoy yourself," says Tunica Sheriff KC Hamp. He maintains there's no reason to avoid the county, adding he's upping patrols and working with neighboring police departments.
"We're going to continue to hunt this person down," he says.
"I hope they do because evidently it's either someone very angry or very sick," Oliva says. "Either way it goes they don't need to be behind the wheel of a car."
Tunica sheriff's deputies are still working the case, saying they're checking new leads and reminding everyone to think about safety and security.
