DESOTO COUNTY, MS- (WMC-TV) - The Mississippi Bureau of Investigation said it has gotten hundreds of tips, but none of them have cracked the case of the highway killer yet.

They will continue to investigate each and every one as if it may be the tip they need to catch the person responsible for two shooting deaths on North Mississippi highways.

Investigators said there is a chance the killer could cross state lines and they are on high alert.

As investigators continue to dig up new leads, police and sheriff's deputies are being vigilant in search of anything unusual.

Two people were shot and killed on the side of Mississippi highways in the month of May.

One of the victims was 74-year-old Tom Schlender from Raymond, Nebraska.

Leaders of New Albany, MS have created a plan to build a memorial park to honor a beloved wife, mother and community servant killed in an attempted home invasion. Amanda Price, 31, speech pathologist for New Albany public schools and wife of football coach Ron Price, was shot and killed on December 5, 2011.

The accused gunman, 20 year old Craig Baker, lived in a trailer park within walking distance of the Price home. New Albany City Councilman Johnny Anderson has proposed buying the seven acre trailer park property and transforming it into the Amanda Price Memorial Park.

I call them "wave" payments. Payments made either with a credit card or a smart phone by simply "waving" the card or phone over a payment terminal. The terminal detects a chip or app that relays payment information via radio frequency.
