Handlen is accused of killing Kathryn-Mary Herbert, 11, and Monica Jack, 12. He has multiple convictions as a violent sexual predator dating back to 1969.
The accused has kept a low profile in recent years, but starting in 1969, he was convicted of a series of sexual offences.
Over the years, some investigators and victims' family members believed Handlen was responsible for killing the two girls, but there had not been enough evidence to lay charges.
Police aren't saying exactly what new facts have come to light, but now believe he is the killer of Herbert and Jack.
