TAMPA - UPDATE: An Amber Alert was issued by the Florida Department of Law Enforcement around 1:15 p.m. Wednesday for the two missing children.
An arrest warrant has been issued for Joshua Hakken for multiple crimes including Kidnapping - 2 counts Interference in Child Custody - 2 counts Child Neglect - 2 counts False Imprisonment -1 count Burglary with a Battery - 1 count Grand Theft Auto - 1 count.
His wife, Sharyn Hakken, has not been charged with any crime so far.
Detectives believe that she is traveling with her husband and children and may have been driving the second vehicle that picked up her husband and children after they left the grandparents' house.
A grandmother was tied up at a Tampa home Wednesday morning and the two children in her possession were taken by their parents in what investigators are calling a parental abduction/kidnapping. The parents are considered armed and dangerous.
Investigators say Joshua Michael Hakken, 35, entered the home of the children's grandmother at 14040 Shady Shores Drive around 6:30 a.m. She is the maternal grandmother of Chase Hakken, 2, and Cole Hakken, 4. It's believed Hakken's wife, 34-year-old Sharyn Hakken was waiting outside.
Detectives did not know if the children were taken at gunpoint, and it was not certain if the mother was directly involved in the abduction.
The grandmother's husband, the children's grandfather, had left for work and was not home at the time the toddlers were taken away.
Joshua Hakken tied up the grandmother, took the children and fled in Hauser's 2009 silver Toyota Camry, which was later found a few blocks away, investigators said.
Reporters were told at a Wednesday afternoon news conference the State of Louisiana took away the parents' parental rights and gave the grandmother temporary custody after a series of incidents.
Detectives believe the children could possibly be in a black 2006 GMC Sierra registered to Hakken. The truck, with Florida tag number U95KT, was thought to be pulling a 2012 Forrest River pop-up camper, but the camper has been located in Louisiana.
According to earlier information, the couple lost custody of the two boys after attending an anti-government rally in Louisiana. The father was charged with possession of drugs in the presence of the children.
But many details are unclear.
According to a sheriff's statement, "We still have un-answered questions from the events in Louisiana prior to today's events here in Hillsborough County. We are working closely with the FBI and government officials in the State of Louisiana to attempt to obtain a better picture of the history of this family and the circumstances which lead to the removal of the children from their parent custody and ultimately the terminations of all parental rights."
After losing custody, Joshua Hakken tried to take the children from a Louisiana foster care facility, according to the statement. He beat on the front door while waving a gun. When he was unable to get in, he fled.
The boys have been with their grandmother since mid-2012.
Chase Hakken is described as 3', 33 lbs., brown hair and brown eyes last seen wearing pajamas of an unknown color.
Cole Hakken is described as 3' 9", 44 lbs., brown hair and brown eyes, also wearing pajamas of an unknown color.
Joshua Hakken is described as a white male 5 feet 9 inches tall, 175 pounds, with brown hair and brown eyes.
Sharyn Hakken is described as a white female, 34 years old, 5 feet 4 inches tall, 150 pounds, with brown hair and hazel eyes.
Anyone with any information is asked to immediately dial 9-1-1 or call the Hillsborough County Sheriff's Office at 247-8200.
