The search for two missing Tampa boys taken by their father on Wednesday continues today on Florida waterways from Key West to Pensacola.

As Florida Fish and Wildlife officers are searching offshore along the Gulf of Mexico, the Amber Alert issued for the boys has been modified to include only states that border along the Gulf of Mexico.

An Amber Alert was issued for 4-year-old Cole Hakken and 2-year-old Chase Hakken after authorities say their father, 35-year-old Joshua Michael Hakken, entered his mother-in-law's house in north Tampa, tied her up and left with the children Wednesday afternoon. The children's mother, 34-year-old Sharyn Patricia Hakken, is believed to be with them.

According to the Hillsborough County Sheriff's Office, other agencies, including the FBI, continue to aid in the search for the family.

"We continue to have full assistance and mutual cooperation from the Federal Bureau of Investigation," said Sheriff's Office spokesperson Det. Larry McKinnon. "The US Coast Guard, the Florida Department of Law Enforcement, the Florida Fish and Wildlife Commission and many other law enforcement agencies from around the country."

Father purchased a sailboat

On Friday, authorities said they've obtained information that Joshua Hakken recently purchased a sailboat.

At least one witness said the 25-foot boat was spotted going underneath the John’s Pass Bridge last week.

The sheriff's office says Hakken has sailed before.
"I don't want to say extensive, but we do know he has some sailing training and some sailing experience, so he is capable of operating that boat,” said McKinnon.

The boat is described as a 1972 Morgan 25M (25 foot) sailboat, blue bimini top, white mainsail, boat deck and cabin are white, hull is blue with “Salty” and a paw print in white on both sides with a white stripe near water line, bearing Flo.

SUV located

On Thursday evening, officials located the vehicle they believe the boys were traveling in with their parents. The 2006 GMC pickup truck belonging to the family was located in the John's Pass Parking Garage located at 12901 Gulf Blvd in Madeira Beach.

Officials said the vehicle was located after receiving a tip.

The Hillsborough County Sheriff's Office, which set up a command post at its Falkenburg Road office to receive calls and tips regarding the case, said it is following numerous leads. The Amber Alert has expanded to nearby states Georgia, Alabama and Tennessee.

More details on the children

Chase Hakken is 3 feet tall, weighs 33 pounds, has brown hair and brown eyes.  He was last seen wearing pajamas. Cole Hakken is 3 feet 9 inches tall, weighs 44 pounds, has brown hair and brown eyes.  He was also last seen wearing pajamas.

Deputies spent Wednesday afternoon and evening at the parents' home, searching for any clues that might indicate where they would go. Detectives said the parents should be considered armed and dangerous.

Anyone with any information is asked to call 911 or to call the Hillsborough County Sheriff's Office at (813) 247-8200.

Previous attempt to take the children, officials say

According to authorities, Hakken was previously involved in an attempted armed abduction of their children in Louisiana.

Officials said they have so far been able to determine that Joshua Hakken was arrested in a hotel on multiple drug charges in St. Tammany Parrish, Louisiana, where he had just attended some type of anti-government rally.

Slidell police say were called to the hotel in June in reference to a disturbance involving Mr. and Mrs. Hakken. Police say when they arrived the parents were acting in a bizarre manner that alarmed officers.

Police say they were talking about “completing their ultimate journey” and were traveling across the country to “take a journey to the Armageddon.” Police say both of the children were present in the hotel at the time.

Police say based on the parents’ behavior and the fact narcotics and weapons were inside the hotel room, officers called the Office of Child Services, who determined the children were in danger and needed to be taken into custody and temporarily placed in a foster home.

"This is not really about anti-government at this point," said David Couvertier, FBI. "Individual beliefs, people in our country should believe in whatever you want to believe in. It's the manner in which the kids have been taken is what concerns law enforcement and the reason we've taken the steps we have taken."

Joshua Hakken was placed under arrest and charged with possession of marijuana, possession of drug paraphernalia, and the use of a controlled and dangerous substance in the presence of minors. Officers also took custody of the guns.

Two weeks later, police say they were notified Joshua Hakken had shown up at the foster family home with a firearm demanding the return of his children. The foster parents called 911 and police say Hakken fled without his children.
