MEMPHIS, TN- (WMC-TV) - She was a good Samaritan, who thought she was helping a woman and her infant child. Helping until that woman shot her, stole her car, and left her for dead. She would have died had another good Samaritan not jumped in.

Three worlds are colliding in this story of heroism and forgiveness as the woman who fired the gun breaks her silence.

"Like any typical day, I was coming home from work. I noticed a young woman with a baby," said Heather Fox. "I said, 'Are you OK?' My heart went out to her. I said, 'Let's go.' I said 'I need to know where we're going.' And she said in a really stern, harsh tone, 'I said just keep driving.' She had a .40 caliber gun and she was pointing it at me. The panic was really starting to set in. I wanted the situation to be over. I opened the door and my instinct told me to bend over. And that's when she fired. And I began to run and collapsed on the ground."

MEMPHIS, TN- (WMC-TV) - Four members of the same family are now charged in connection with the murder of one of their own.

Melrose High School student Cardarius Webb, 15, was shot and killed in April. His brother was charged with the murder days later. Now, his mother and two other siblings are charged with harassing and threatening the woman they thought committed the crime.

Hundreds of people crowded the corner of Spottswood Avenue and Pendelton Street to watch the investigation unfold after the shooting.

A woman who lives in the house in front of where Webb died was originally questioned. She was then reportedly harassed and assaulted by his family who blamed her for the death.

The teen's mother, Bernestine Webb, is accused of telling the woman while striking a metal pipe on the ground, "You took my son's life, I'm going to take yours."

MEMPHIS, TN- (WMC-TV) - Most of the time a tip is automatically included with the bill when a table at a restaurant has a large party. Now, some Mid-South restaurants are imposing auto-gratuity polices on parties as small as one person.

The new trend in the restaurant industry is getting an icy reaction from some customers. Gratuities from 15 to 18 percent are being automatically added to checks no matter how big, or small, the party.

"I may have a problem with having to tip 18 or 15 percent if I have bad service," said customer Amber Long.

They are called auto grats.

"If I'm being forced to tip and the service has not been good then that presents a problem," said customer Rick Harrell.

The Half Shell on Winchester Road adds auto grats to every receipt after 10 p.m. East End Grill on Winchester Road also does it after 6 p.m.
