(CNN) -- A Florida judge has signed an emergency "pickup order" authorizing law enforcement officers to get the 5-year-old son of country singer Mindy McCready, a court spokeswoman said Thursday.
Earlier this week, McCready was told in a different court order to return the child -- of whom she does not have legal custody -- to authorities.
The child was not brought in, prompting Judge James H. Seals to sign the emergency order around 4 p.m. Thursday , said Sheila Mann, a spokeswoman for Florida's 20th Judicial Circuit court.
"The child is now an official missing person," said Aimee McLaughlin, a spokeswoman for the Children's Network of Southwest Florida, the lead agency for child welfare services
McCready has not been charged with any crime. The latest order means that law enforcement officers now have the right to take custody of her son, Zander, who she has said is with her, even if he is not in Florida, McLaughlin explained.
The 36-year-old singer never contacted the Children's Network after the initial court order, according to McLaughlin. And 20th Judicial Court official Penelope Rose also said late Thursday afternoon that the singer hadn't delivered the child to court authorities.
The boy's father, Billy McKnight, said that he talked with Zander by phone on Thursday night and said the boy "sounded OK." But McKnight said he wasn't sure when he'd see the boy again.
"I don't know if (McCready) plans on bringing him back," McKnight, himself a country singer, told HLN's Jane Velez-Mitchell. "She didn't lead me to believe that she was going to."
McCready's parents have legal custody of the child, while the entertainer has visitation rights, said Terri Durdaller, spokeswoman for the Florida Department of Children and Families.
A caseworker reported no problems during a visit last week, but that was not the case Tuesday, McLaughlin said.
That day, a caseworker who went to the home of McCready's father could not find McCready or the child, Durdaller said. The worker became "concerned about the well-being" of the boy and contacted law enforcement, according to a report obtained from the Cape Coral Police Department.
On Wednesday, McCready told HLN that her son is fine.
Cape Coral police spokesman Lt. Tony Sizemore told CNN the issue was a "civil matter" and there was no missing child alert. Meanwhile, McCready's publicist issued a statement saying McCready "has not been charged with illegal wrongdoing."
"Ms. McCready's number one priority has always been, and continues to be, the safety of her son," publicist Kat Atwood said in the statement. "The 5-year-old boy has been with his mother for more than 30 days; law enforcement officials spoke with the child and saw Zander via Skype yesterday."
McCready has asked a court to have her son returned to her out of concern over his safety, Atwood said.
With the emergency pickup order now official, local law enforcement will update the Florida Department of Law Enforcement and the FBI's National Crime Information Center about the case, according to McLaughlin.
"Once the child is located, we will make plans to bring the child back to the home of his maternal grandmother, which is the legally approved place," she said.
McLaughlin said that Zander's safety was state authorities' top concern.
"In any case, not just this one, we want to ensure the well-being of the child," the spokeswoman said.
McCready burst on the music scene in 1996, with the debut album "10,000 Angels" and the chart-topping country hit, "Guys Do It All the Time."
In addition to romances with musician David Malloy and actor Dean Cain -- as well as admitting to an affair with baseball player Roger Clemens, which he didn't confirm or deny -- her official biography also touches on her career stalling as well as her "explosive relationship" with McKnight.
She has waged a public battle with drug addiction over the past several years, including being a participant in the 2009 season of the reality TV show "Celebrity Rehab with Dr. Drew." She was rushed to a Fort Myers, Florida, hospital last year, Cape Coral Hospital spokeswoman Karen Krieger said, after a 911 caller claimed the singer had overdosed.
McCready is currently pregnant with twins, according to her publicist. Her official biography notes her 2010 "triumphant return to her first love, music ... after an eight-year recording hiatus" with the album, "I'm Still Here."
McKnight, the father of her child, refused to speculate Thursday night on McCready's current mental state or sobriety. He told HLN that he wants her to "get herself healthy," so the two can work together "as two adults ... to make (their son's) life better."
"My biggest concern is the fact that Zander is used to being here in Florida," said McKnight, referring to the state that he and the boy call home. "I'm worried about him just being moved around."
