Rex Heuermann's family defend creepy crime scene scrapbook found on kitchen table as Gilgo Beach cops continue search of their home

The attorney representing Gilgo Beach serial killer suspect Rex Heuermann's children has defended their apparent possession of a creepy book of crime scene photos from different killings. 

Police continue to search the family's home in Massapequa Park, Long Island, but are yet to reveal what exactly it is they are looking for. 

Heuermann was arrested in July and initially charged with killing Melissa Barthelemy, 24, Megan Waterman, 22, and Amber Lynn Costello 27 in 2010 and 2011.

Investigators and state police swarmed the Massapequa Park home of alleged Gilgo Beach serial killer Rex Heuermann (pictured in court in February) with a new search warrant

In February, he was also charged with the murder of Maureen Brainard-Barnes, 25. 

The women he is said to have killed were among 11 victims whose bodies were found along the Long Island coastline between 2009 and 2011. 

Yesterday, police sources told Fox News the family was still keeping a copy of Death Scenes: A Homicide Detective’s Scrapbook, on the family's kitchen table.

It had been inventoried as part of the initial search of the home last July and returned to the family.  

The book is a compilation of photographs from a California homicide detective's career. 

Quite why the Heuermann's had it, or which one of them bought it, remains unknown.  

According to police sources, cops found this book on the kitchen table in the family home. The book is by a former LAPD homicide detective and contains gruesome photos from the crimes he investigated 

Accused Gilgo Beach serial killer Rex Heuermann is 'not capable' of the brutal murders he's been accused of, according to his estranged wife Asa Ellerup (pictured)

The first victim, 24-year-old Melissa Barthelemy, was discovered by Suffolk County Police on December 11, 2010. The body of Megan Waterman, 22, from Maine, was found two days later

Heuermann is also charged with killing Amber Costello (left) and  Maureen Brainard-Barnes (right) 

It is not clear at this time what prompted the search of the Long Island property or what officials were looking for, but multiple law enforcement agencies were present, including a command center

In a statement to DailyMail.com, Vess Mitev, the lawyer representing Victoria Heuermann, 26 and Christopher Sheridan, 33, said neither he nor his clients had 'knowledge' of such a book. 

He then offered a potential defense of them. 

'It's not against the law to have books!' he said. 

Investigators have long maintained that Heuermann, an architect who worked in Manhattan, committed the killings of the sex workers while his family were out of town. 

His estranged wife Asa continues to attend court hearings neither in defense of him or in support of the victims.

Instead, she says she wants to hear all the evidence before forming an opinion. 

Heuermann is accused of targeting the women by meeting up with them via their ads. 

He is also accused of tormenting the victims' families after killing them.
