The ex-boyfriend of a Casa Grande mother sparked an Amber Alert on Thursday morning when he told her family she was a threat to her children, according to authorities.
Jessica Brown, 31, turned herself and her children in to Casa Grande police when she heard the Amber Alert. She was not charged and was released by Casa Grande police Thursday morning.
Pinal County sheriff's deputies had been searching for Brown after she was suspected of abducting her four children from their Casa Grande home in a red minivan, forcing the Amber Alert to be issued.
Brown's ex-boyfriend, who is the father of three of the children and lives in Phoenix, had told her family that she was a threat, sparking the family's concern for the welfare of Brown and the children, said sheriff's Lt. Tamatha Villar.
Brown, who has legal custody of the children, said she was surprised when she heard about the Amber Alert and turned herself in to police about 5:30 a.m., Villar said.
Brown and her four children, Sarah Goree, 15, Michaela Brown, 8, and twin 1-year-old sons, Devin and Drake Brown, were unharmed, Villar said.
Villar said Brown and her children were sleeping in their Chevrolet van at a Casa Grande park overnight. Brown said she has been looking for a place to live and a job, Villar said.
Brown told detectives she refused to answer their calls because she didn't recognize the number, and that text messages between Brown and her family contained no threats to the children, Villar said.
Brown said she was concerned the incident would scare away potential employers and hurt her chances for a new home, Villar said.
A detective found Brown and the children temporary housing "until she can get back on her feet," Villar said.
Villar said the children never appeared to be in danger, and that they were clothed and clean.
Brown and the children had been in Phoenix the past couple days, but have friends and family in Casa Grande, Villar said.
Deputies initially said Brown's ex-boyfriend told the family she had threatened to either drive the vehicle onto railroad tracks in front of an oncoming train or into oncoming traffic on a freeway.
Villar said the ex-boyfriend, whose name was not released, could face possible charges of false reporting, a misdemeanor.
The Amber Alert was issued about 3:20 a.m. Thursday
