Detectives have been praised for collecting and preserving DNA materials during the original Easey Street investigation at a time when little was known about the use of the science in criminal cases.
A criminologist has praised a decision by detectives to collect and preserve DNA samples during the original 1977 Easey Street investigation.
Their bodies were found when neighbours went to investigate the crying of Ms Armstrong's 16-month-old boy who police say had been stranded in his cot for several days.Ms Armstrong had also been sexually assaulted and police believed Ms Bartlett was killed when she tried to help her housemate.The case became known as the Easey Street killings and became notorious for the level of violence, the toddler's plight and the absence of an arrest for 47 years.
"It's really just a case of being very dogged and determined and really wanting to get answers for those families." "It's fairly unusual forensically for this type of situation to arise, particularly after 50 years, near enough," he said.But he said Easey Street was not the first case where a suspect had been arrested after such a long period.
