Ahead of the second anniversary of the 29-year-old’s death, the PSNI thanked the community in Derry for their “incredible response” throughout the investigation.
Ms McKee was shot dead by dissident republicans in Derry on Thursday, April 18, 2019 as she observed rioting in Creggan’s Fanad Drive.
The New IRA admitted responsibility for the murder.
One Derry man, Paul McIntyre, 52, has been charged with Ms McKee’s murder.
But police are still searching for evidence to charge the teenage gunman who fired the fatal shot.
Her death helped kickstart political talks leading to the resumption of Stormont powersharing last year.
Detective Superintendent Jason Murphy of the PSNI’s Major Investigation Team, said: “As we approach the second anniversary of the murder of 29 year old Lyra McKee on 18 April 2019, our thoughts are very much with her family and partner at this very sad time.
“Lyra’s family not only continue to mourn for her but also for her mother, who sadly passed away after Lyra’s murder.
“One man was charged with murder, hijacking, arson of a vehicle, riot and petrol bomb offences, and a second man was charged with hijacking, arson of a vehicle, riot and petrol bomb offences.
“A third man was charged with possession of a firearm with intent to endanger life and possession of a firearm in suspicious circumstances.”
This third man was charged with possessing the firearm that was used in Lyra’s murder, but has not been charged in connection with the events of April 18, 2019 directly.Detective Superintendent Murphy added: “The investigation into the murder of Lyra still remains very active and I would like to thank the community for their incredible response throughout our investigation.
“I want to re-state the commitment of the police service to work with the community as we collectively seek to release communities from the influence of terrorists.”
