The sister of a missing Florida woman said Tuesday that "nobody is ruled out" in the case of the mother of three who disappeared after a taped episode of "The People's Court" aired that featured the young woman.

Michelle Parker, of Orlando, Fla., was last seen dropping off her 3-year-old twins at her former fiance's home on Thursday, the woman's sister, Lauren Erickson, told Fox News.

Erickson said her brother received a suspicious text message from Parker's phone at 4:26 p.m., indicating she was in the Waterford area.

"She doesn't send one-word text messages," Erickson said.

The 33-year-old mother disappeared on the same day an episode of the court show aired featuring her and her ex-fiance, Dale Smith, who is the father of her twins.

Parker and Smith had appeared in court over a dispute about a $5,000 engagement ring. Parker described a tumultuous relationship with Smith that at times she said became violent.

"He gets pretty malicious and vindictive," Parker said on the show, "and he's a mean person especially when he's been drinking."

"He shouldn't have put his hands on me and he shouldn't have put his hands on me prior. He shouldn't have left me three or four times over the past year and a half that we've been together," she said.

Erickson suggested that Dale was an unlikely suspect in her sister's disappearance but said "in my opinion, nobody is ruled out by any means."

"Who would want to hurt the mother of their children?" Erickson said. "I don't see how in any way he would benefit from it."

Parker's Hummer sport-utility vehicle was found abandoned a day later on the west side of Orlando, police officials said.

The woman's mother, Yvonne Stewart, said on NBC's "Today" show Tuesday that she believes her daughter, who is a well known bartender in the Orlando area, was kidnapped after being the victim of a random carjacking.

"I know in my heart of heart that she's been carjacked, that the people saw an expensive car and a girl who looks like she has money and I know they've made a mistake and I know that they want to fix this and I forgive them," Stewart said.

"It's Thanksgiving. She wants to come home to her babies. We want her home."

Volunteers from Texas Equusearch, a non-profit search and recovery team, arrived in Orlando Saturday and are working with authorities and Parker's family in coordinating the search. Search dogs, ATVs, and men on horseback are all being employed as rescuers try to locate her.

Parker is described as 5 foot, 6 inches tall with short, dark brown hair. Anyone with information on her disappearance is being urged to call the Orlando Police Department at (321) 235-5300.
