TAMPA - The Hillsborough County Sheriff's Office released a 911 call made by the Tampa grandmother of two missing boys.
In the phone call, you can hear Patricia Hauser. "My son-in-law just kidnapped my two, my two grandchildren. They've been in my state custody. He's had been missing for... Not yet. They're in state custody. They're under the state custody-- not supposed to be near them. He's been missing for 9-months. He tied me up. I was able to remove myself with a pair of scissors."

The boy's maternal grandmother made the 911 call after deputies say her son-in-law zip-tied her inside her Tampa home and kidnapped her two young grandsons Chase and Cole.
"We're working around the clock and focusing on the safe return of the entire family," said Hillsborough County Sheriff's Colonel Donna Lusczynski.
Now FBI agents are working with local law enforcement to find the two and four year old and their parents. They say color billboards are going up around the Southeast and Southwest.
Detectives also say they've received tips about several sightings of the Hakken family in several different states. Authorities in Southeastern Tennessee put out a statewide Amber Alert Wednesday night after a reported sighting near Etowah, Tennessee in the area of Highway 30 and Highway 411. The location is on the edge of the Smokey Mountains.
"We have at this point received tips from various states alleging sightings of the children and family. We are working with our law enforcement partners and the FBI and trying to vet those tips and see if it is accurate information," said Colonel Lusczynski.
At this hour, four states have issued Amber Alerts including Florida, Georgia, Alabama and Tennessee.
"We don't expect or anticipate them hurting the children and we're hoping again that this just comes down to a very peaceful situation where we can resolve the situation and potentially maybe even put the family back together," said FBI Special Agent Dave Couvertier.
Louisiana Police says Joshua and Sharyn Hakken lost custody of the boys after a bizarre encounter in 2012. A Slidell Police Department detective tells us by phone they were called to a disturbance at a hotel.
"Mr. Hakken was in possession of narcotics and he had some weapons with him. At that point in time, he was placed under arrest," said Slidell Police Detective Daniel Seuzeneau.
"They were speaking some bizarre words that alarmed our officers. They were talking about going to California and when I read the report yesterday, it was something towards the effect of they were trying to beat the Armageddon and get to California which was, obviously, very bizarre," he said.
Louisiana detectives say the couple told officers they were trying to beat "Armageddon" and "complete their ultimate journey." They also say the father tried to kidnap the boys at gunpoint from a foster care home in Louisiana but failed.
Law enforcement has characterized the couple at "anti-government" but aren't sure where they are headed or why.
"Anytime something like this happens there's usually at least one person that knows something that's going on and we're hoping that that person will come forward and at least provide some advice or even some input or perspective as to the mindset of what they're really looking to do here," said FBI Special Agent Couvertier.
