Police need help solving four Mid-South cold cases. Two of the cases are murders that happened in Memphis and the other two cases involve women who went missing years ago.

The Shelby County District Attorney announced Monday, March 3, that the rewards are increasing in the unsolved cases. Eyewitness News Everywhere spoke to family membes or the murdered and missing women following the D.A.'s announcement.

"It was a random shooting and my son did not deserve this," says Allen Jacobs. Jacobs' son, Ethan, was shot and killed in May 2007 at McKellar Lake near Presdients Island. Police say the shooter was wearing a light-colored bandana and they say he and another man drove away from the scene in a late 1980s, dark red, four-door Nissan. Police say a man was arrested for the shooting, but the case was dismissed because a witness could not make a positive identification.

Bartlett pediatrician, Dr. Cheryl Pearson, went missing in January 2002. Police say Pearson disappeared after going to a Grizzlies game at the Pyramid in downtown Memphis.

"She had two friends that stopped by and visited with her after the Grizzlies game. We know that. We've interviewed them, so we know she made it home," said an investigator with the Bartlett Police Department.

Police say the only leads they have in the case are a phone call made to Pearson's home from a gas station pay phone and her car, which was found two days after she disappeared at a nearby apartment complex. Police say they do believe foul play was involved, and the case is now being investigated as a homicide.

Another woman, 18 year-old Kirsten Kryszak, disappeared on New Year's Day 2001. Police say Kryszak went to a New Year's Eve party in Midtown Memphis and was spotted driving a 1988 blue Ford Aerostar van near the intersection of Poplar and Highland. Police have never found Kryszak or the van. Kryszak's mother, Karen St. Mary, was in attendence when the D.A. announced the increase in rewards.

"I'm here as a voice and with all the hope I have in my heart to put closure on this because someone knows something."

Another cold case: The murder of Alicia Fitch and her three year-old son. Fitch and her son were found stabbed to death in their apartment at Ketchum and Airways on September 10, 2001. Police say their murder did not get much attention because it happened the day before 9/11. Police say they hope to get new leads that will help solve this crime, as well as the others.

Tennessee Governor Phil Bredesen is giving $5,000 of state money to the reward funds for these cases.

The total reward for the Ethan Jacobs case is now $6,000.
The total reward for the Cheryl Pearson case is now $41,000.
The total reward for the Kirsten Kryszak case is now $18,000.
The total reward for the Alicia Fitch case is now $6,000.
