A 6-year-old Texas boy whose mother has given various stories to explain his absence since last fall is believed to be dead, police said Thursday.

Noel Rodriguez-Alvarez was last seen around the time his mother gave birth to twin girls in October, Everman police Chief Craig Spencer said at a news conference. He said searches for the boy's body have been focused near the family's home in Everman, located just south of Fort Worth.

Around the time that Noel was last seen, he was described as "appearing unhealthy and malnourished," Spencer said. On March 31, arrest warrants on charges of abandoning and endangering a child were issued for the boy's mother, Cindy Rodriguez-Singh, and her husband, Arshdeep Singh.

They are believed to have flown to India on March 22 along with six children. Two days earlier, police had been asked by the Texas Department of Family and Protective Services to do a welfare check on the children at the couple's home. During that visit, Rodriguez-Singh told officers that Noel was staying with family in Mexico.

Spencer said that Rodriguez-Singh "has been known by relatives to be abusive and neglectful to Noel." Also, he said, investigators learned through interviews that Rodriguez-Singh had referred to Noel as "evil, possessed or having a demon in him" and believed he'd harm the twins.

Police have said that Noel suffers from numerous physical and developmental challenges.

"Relatives and witnesses stated that food and water were often withheld from Noel because Cindy did not like changing Noel's dirty diapers," Spencer said. "A relative even witnessed Cindy strike Noel in the face with keys because he drank water."

Spencer said that on Nov. 1, 2022, Rodriguez-Singh got passport photos for all of the children living with her except for Noel. And then, the next day, she applied for passports for herself and all of the children except for Noel.

Spencer said that in November, Rodriguez-Singh began to try to explain Noel's absence with "various stories," including that he was either with his biological father or aunt in Mexico, or that she'd sold him to a woman in a grocery store parking lot. Spencer said that investigators have looked into all of those stories and none were true.

Actor Lance Reddick’s family attorney has released a statement disputing his cause of death. Reddick was found dead in his home on March 17.

Attorney James Hornstein said Thursday that the actor’s lifetime of personal fitness seems to contradict a statement from the coroner that Reddick died of heart disease, according to People. He also said Reddick’s body did not undergo an official autopsy.

According to Reddick’s death certificate, which TMZ obtained and made public, his cause of death was ischemic heart disease and atherosclerotic coronary artery disease.

Hours after its release, Hornstein said "the information appearing on the death certificate is wholly inconsistent with his lifestyle," according to People.

"I have represented Lance Reddick for many years and continue to represent his wife Stephanie. The coroner's statement on the death certificate is not a result of an autopsy. No autopsy was performed on Lance. To my knowledge, no medical examination of Lance during his lifetime ever indicated such conditions," Hornstein added.

"Lance was the most physically fit person I've ever known. He exercised daily at his home gym, including extensive cardio work, and the availability of gym facilities was a contractual requirement for his work away from home," the attorney said. "He ate as if a dietitian was monitoring his every meal."

He concluded, "On behalf of Stephanie Reddick, the death certificate information is not corroborated and is inconsistent with the facts known to the family."

The Baltimore-born Reddick was 60 when he died "suddenly" due to natural causes Friday morning, his publicist Mia Hansen confirmed in a statement to the Associated Press.

He was perhaps best known for his leading role as straight-laced Baltimore police lieutenant Cedric Daniels on the hit HBO series "The Wire."

He also starred as a loyal hotel manager Charon in the John Wick films — including the most recent release, "John Wick: Chapter 4," which is still in theaters.

The franchise’s lead star Keanu Reeves candidly spoke out about Reddick after his death and expressed that it "f---ing sucks he’s not here."

"Lance was a beautiful person, a special artist… a man of grace and dignity… such a passion for his craft," Reeves said during an interview with Deadline.

On the day of Reddick's death, Reeves and "John Wick" director Chad Stahelski released a joint statement to Deadline saying, "We are deeply saddened and heartbroken at the loss of our beloved friend and colleague Lance Reddick.

"He was the consummate professional and a joy to work with. Our love and prayers are with his wife Stephanie, his children, family and friends. We dedicate the film to his loving memory. We will miss him dearly."

Reddick was also a prolific voice actor in several video game titles, including a central character in the "Destiny" franchise.
