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) - Friends of Heather Palumbo-Jones said it was a weight battle in more ways than one for a Germantown couple whose marriage ended in murder.

According to friends, Chris Jones was obsessed. He was addicted and dependent on his estranged wife, and could not let go.

"She told me he told her to gain the weight back. I said, 'You've got to be kidding me.' He was a control freak," said friend Cari Cooper.

Friends described Palumbo-Jones' husband as a man spiraling out of control as the marriage collapsed.

They said Palumbo-Jones, a teacher at Frayser Achievement School, met Chris Jones when she was 19 years old. She was 160 pounds overweight.

Friends said after working out and losing the weight, Chris felt threatened.

"He was losing his grip on her. She was like a butterfly who came out of a cocoon," said Copper.

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.
