Crystal McDowell’s body was located earlier on Saturday, according to Texas EquuSearch, which did not release any additional details.

BAYTOWN, Texas ― Dozens of members of Texas EquuSearch, many of whom are still reeling from the effects of Hurricane Harvey, gathered in south Texas this week to search for missing realtor Crystal McDowell.

“Several of our people have water in their homes or they are nearly destroyed, and they left what they were doing to come out here,” Texas EquuSearch founder and director Tim Miller told HuffPost on Wednesday. “We have about 100 people out here ― ground searchers, ATVs, drones, boats and the list goes on.”

McDowell, a 37-year-old mother of two from Baytown, was last seen on the morning of Aug. 25 ― the day before Harvey ravaged the area. She was captured on video leaving her boyfriend’s house and was reportedly on her way to pick up her children from her ex-husband, Steven McDowell. The Chambers County Sheriff’s Office has said it does not believe the missing woman was a victim of the storm. Authorities suspect foul play in her disappearance, but have yet to name any suspects or persons of interest.

McDowell’s black C-class Mercedes was found on Aug. 27, submerged in water at a Motel 6 in Mont Belvieu. Authorities said they suspected it had been parked there prior to the storm.

About two dozen members of the Army National Guard joined EquuSearch, making their way through thick underbrush along West Bay Road in Baytown, north of Highway 99. Searchers focused on the Cedar Bayou and surrounding areas.

“Information came in on the investigation that [authorities] want this area searched,” Miller said. “We’re going where they want us to go and we’re spreading out from there.”

Volunteers spent about 12 hours searching for McDowell on Wednesday and were back at it on Thursday morning.

“We flew this area with two different kinds of aircraft,” said Gene Robinson of Drone Pilot, Inc. “We used high-resolution cameras, and when we came across things we had no way of identifying, we sent in ground crews with GPS coordinates.”

Searches are ongoing this weekend.

Miller coordinated the search efforts just days after rescuing members of his family who were trapped in a Dickinson attic with rapidly rising water.

“My granddaughter calls and she’s panicked,” Miller told HuffPost of receiving a call from Natalie Weir, 28.

“Grandpa, we’re in the attic,” he recalled her saying. “We called 911 and they can’t even tell us when they’re going to get us. We’ve got so much water down the stairs and they told us don’t go down the stairs because the electric is still on, so you don’t want to take a chance on getting electrocuted.”

Two of Miller’s other grandchildren, a 1-year-old great-granddaughter, Miller’s ex-wife and a dog were also trapped. Miller, who had 4 feet of water in his own driveway, managed to get his boat running, and headed over to the house where his family was trapped.

“At that point in time I was really fearing that I lost the remainder of my family,” he said. Luckily, he and Texas EquuSearch member Oden “Odie” Walder were able to get everyone out safely.

Miller said he’s grateful his loved ones are safe, and that his heart now goes out to McDowell’s family.

“We certainly feel the worst has happened and the sooner we find her the better chance there will be evidence for law enforcement to move forward with the investigation,” he said. “The biggest issue here is that she went missing before the storm got here. So, did she float into an isolated area that’s more difficult to get to? That’s the challenge, but hopefully we can bring some closure to this case.”

Crystal McDowell is described as 5-foot-4 and about 110 pounds. She has blonde hair and green eyes. She was last seen wearing a pink and purple dress. Her family is offering a $10,000 reward for information on her whereabouts.

Anyone with information is asked to contact the Chambers County Sheriff’s Office at 409-267-2500.

Tamala Wells

Tamala Wells, of Detroit, disappeared on Aug. 6, 2012. Her mother, Donna Wells-Davis, learned of her daughter's disappearance on Aug. 7, 2012, when she received a phone call from her granddaughter, who was then 6 years old. The little girl said that her mom, then 33, had gone out the previous night and never returned.



The mystery deepened when the Pontiac that Wells had supposedly been driving was found abandoned just a few blocks from her home.



In an interview with HuffPost, the father of Wells' daughter denied any involvement in Wells' disappearance, but he didn't deny how he feels about the mother of his child -- or about the child herself.



"She gives me a headache," Rickey Tennant said. "[Wells] used to give me a headache, but I dealt with it, and I'm looking at it right now as 'one headache is better than two headaches.'"

Joy Hibbs

On April 19, 1991, the body of 36-year-old Joy Hibbs was found inside her burned-out home in Bristol Township, Pennsylvania. According to retired Bristol Township Detective Lt. Richard Bilson, the scene inside the bedroom where Hibbs was found was horrific.



"She was lying face-up on a mattress that was nothing but springs," Bilson told HuffPost. "Her body was black -- completely burnt beyond recognition. She looked like a mummy and the entire room was charred."



Bilson said fire investigators initially thought Joy Hibbs was the tragic victim of a house fire. The following day, a coroner confirmed part of that theory -- her death was tragic, albeit no accident. "The coroner advised us she died before the fire started," Bilson said. "He located five stab wounds, to her neck and chest, and there was a computer cord wrapped around her neck. At that point, it became a homicide investigation."

Terry And Darleen Anderson

In October 2005, an unknown intruder brutally murdered Terry and Darleen Anderson. The crime -- LaGrange County, Indiana's first double homicide -- shocked their rural community and left many deep emotional scars.



Inside the couple's home, Darleen was found still dressed in her nightclothes, slumped over on the couch. A book was in her lap and a bowl of popcorn was sitting next to her. Someone had viciously attacked the 57-year-old woman while she sat relaxing inside her home.



Outside, in a nearby pole barn, lay Darleen's husband of 25 years. Like his wife, the 59-year-old had been brutally bludgeoned to death.



With few clues to follow, the case quickly went cold. Many questions still remain.

King's mother, Gayle King, described her son's disappearance as inexplicable. "Neal was a kind person and an amazing son," she said. "That's just how he was. He had strong family values. Family for him was everything."

Judith Geurin

Relatives of Judith Geurin last spoke with the 45-year-old mom in January 1991. Geurin's disappearance is rooted in events that transpired in July 1988, when her husband of 18 years, 57-year-old Joseph Geurin, died of a heart attack. According to family members, Joseph's death devastated her and shattered the family. The grief, they said, was so severe that her mom turned to alcohol for solace.



By January 1989, Judith Geurin had collected more than $250,000 in life insurance and pension funds granted to her following her husband's death. She sold the family's four-bedroom, colonial-style house and took out a mortgage on a two-family duplex in nearby Troy. Geurin's children, then ages 21, 16, 13 and 11 -- moved into the duplex. However, unbeknownst to them until moving day, their mother had other plans.



Instead of following her children, Geurin moved in with 27-year-old Curtis Pucci. In 1990, Geurin and Pucci moved some 200 miles southwest of Albany to Sodus Point. Even though she had all but abandoned her children, Geurin kept in regular contact with her eldest daughter until January 1991, when Geurin vanished without a trace.

Anita Knutson

In 2007, Anita Knutson was an 18-year-old Minot State University student majoring in elementary education. Knutson was, according to her family, exceptionally responsible for her age and juggled three part-time jobs while attending college.



Despite a busy life, she kept in regular contact with her family. So, when she went two days without returning phone calls, her father went to her off-campus apartment on June 4, 2007.



When repeated knocks to the door of her 4th Street apartment went unanswered, her father had the building manager open the door. When the concerned father stepped inside, his worst fears became a reality when he found his daughter's lifeless body on the floor of her bedroom.



Authorities determined the young woman had been stabbed multiple times, more than a day before her body was found. The murder weapon, a bloody knife, was found discarded in a sink. Detectives also determined someone had cut the screen to Knutson's bedroom window, presumable to gain entry into her apartment.



Despite an intensive investigation, authorities were unable to identify a suspect or person of interest in her murder and the case went cold.

JonBenet Ramsey

On Dec. 26, 1996, 6-year-old JonBenet Ramsey was found bludgeoned and strangled to death in the basement of her family's Boulder, Colorado, home. A ransom note from an anonymous group of individuals "that represent a foreign faction" asking for $118,000 in exchange for the safe return of JonBenet was found just hours before, but no call ever came from a kidnapper and it was never linked to a murderer. The entire Ramsey family was cleared of any involvement in the murder of JonBenet back in 2008, thanks to then newly discovered DNA evidence, according to 9News.



Beginning in 2010, investigators reopened the case and launched a fresh round of interviews with witnesses that could provide more insight into the murder, according to ABC News, but nothing fruitful came of those interviews. The DNA evidence still points to an "unexplained third party" that serves as a vague lead for authorities still pursuing the case, Time magazine reported. Boulder police have tested more than 150 DNA samples and investigated nearly the same amount of potential suspects in their ongoing investigation, but none have ever been linked to the crime.

Each of the homicides occurred along the scenic 23-mile route between Jamestown and Yorktown in Virginia, giving them a ready name: the Colonial Parkway murders. Due to the shared location and other similarities among the deaths, law enforcement officials viewed them as the work of a possible serial killer.

Sarah Kinslow

Sarah Kinslow was last seen by her parents on May 1, 2001, when her dad dropped her off at Greenville Middle School in her hometown of Greenville, Texas, at approximately 7:20 a.m. It was not until after the school day ended that the Kinslows were notified their daughter had not attended any of her classes. When Louise Kinslow spoke to her daughter's friends, they said her daughter was supposed to skip school with them that day and meet up at nearby East Mount Cemetery. Concerned, Kinslow contacted police and reported the teen missing.



Authorities took an article of Sarah Kinslow's clothing from the family home and brought a tracking dog to the school. Investigators were able to pick up her scent where she had exited her father's car. The dog followed the scent around the school and to a location two blocks away, where...
