Eleven people died and 63 were hurt after the IRA's no warning bomb tore through the cenotaph in the Co Fermanagh town on 8 November 1987.
A twelfth victim, Ronnie Hill, died in 2000.
No-one has ever been convicted over the attack, but now 25 years on, there is hope a fresh inquiry can be launched.
A statement from the PSNI said: "The Historical Enquiries Team has concluded its work on the deaths which were caused at the Enniskillen Cenotaph bombing in 1987.
"Staff have updated families on the HET work and will formally hand over to PSNI's Serious Crime Branch who will assess the potential for further work to be progressed."
Arlene Foster of the DUP claimed the police investigation into the bombing "has been reopened" and said "an active line of inquiry is being pursued".
The Fermanagh and South Tyrone MLA continued: "The Enniskillen bomb was an act of horrific savagery. It was motivated by nothing other than a desire to kill and maim. It was indiscriminate. Young and old were injured. It was targeting innocent people. Twenty-five years after the explosion, someone somewhere knows something about the perpetrators."
Ms Foster called on anyone who knows more to come forward.
She said: "Someone knows where the bomb was made, how it was transported and who planned the attack. This wasn't executed by one of two people. A team of people were involved.
"Anyone who can bring any information to the police should do so. Perhaps in 1987 they didn't feel able but as they watch the victims and relatives on Thursday I hope they will be moved to help the police with the investigation."
A memorial service will be held at the scene of the atrocity on Thursday.
