The estranged wife of accused Gilgo Beach serial killer Rex Heuermann is demanding that police return his gun collection.

Attorney Robert Macedonio represents Asa Ellerup, Heuermann's estranged wife. Macedonio says Ellerup has had no source of income since her husband's arrest and now police are focused on the couple's assets.

"It is just a matter of dividing up assets, that's anything from jewelry, to cars, to the house, to the gun collection," says Macedonio.

He says 280 of Heuermann's guns were seized, including collectables from the Civil War and both World War I and World War II. Macedonio says if investigators won't release the guns to Heuermann's family, there might be another solution.

"I understand the optics of returning firearms to the home of an alleged serial killer, so it would be my suggestion if they can be given to a licensed firearm dealer," says Macedonio.

In addition, Macedonia says a dealer could appraise and sell the weapons he believes are worth hundreds of thousands of dollars.

David Adamovich, who owns the largest serial killer collection in the world, says there is a tremendous interest in serial killer and true crime collecting. He says the guns taken from the Massapequa Park home are worth significantly more money because of the accusations against Heuermann.

Ellerup filed for divorce one week after her husband's July 13 arrest. Her attorney says Heuermann was also wearing a watch that has significant value.
