DETECTIVES investigating the sudden deaths of a man and a woman this week are still quizzing four men on Thursday.
The bodies of the two victims, who shared the same surname but were not related, were found within 24 hours of each other.
Olivia Reilly, 29, was found dead at a house she was visiting at Trasna Way around 7.30 pm on Sunday evening.
The following day the body of 36-year-old Noel Reilly was found dead at a house less than a mile away Carrowshee Avenue around midday.
One theory being investigated by police is that they may have died as a result of taking drugs.
The four men – one aged 18, two aged 28, and one aged 32 – were arrested on Wednesday on suspicion of possession of Class A drugs and possession of Class A drugs with intent to supply.
The men were detained following a number of searches in Lisnaaskea on Wednesday by investigating detectives.
Police are still awaiting the results of toxicology tests carried out at post mortem to determine exactly how they died.
