Aidan “Turtleboy” Kearney, a blogger who has brought much attention to the murder case against Karen Read and has advocated for her innocence, has purportedly turned himself in to police on a charge of assault and battery for an alleged Friday incident.

“Attention: Aidan has been framed for A&B. He can prove his innocence, but he also currently has strict bail conditions. He has handed himself into police and is on his way to Dedham District Court. If you can get there, please do. Media is waiting. – admin,” a post on the Turtleboy Facebook page stated at noon.

Kearney, who turned 42 today, was arraigned Friday on 16 counts related to his coverage and advocacy in the Karen Read murder case on in Norfolk Superior Court: eight counts of witness intimidation, three counts of conspiracy to intimidate witnesses, and five counts of picketing a witness. He had been released on personal recognizance with no restrictions in place following his hearing.

There had been a “Be on the Lookout,” or BOLO, order on Kearney issued by the Medfield Police Department, Kenneth Mello, the special prosecutor handling Kearney’s Superior Court case, confirmed to the Herald Tuesday.

Kearney is the editor and writer for the Turtleboy blog, which has historically featured a variety of topics, usually taking aim at people in Greater Worcester and Greater Boston, but has in recent months been primarily focused on the case of Karen Read, a Mansfield woman charged with the murder of her boyfriend of two years, Boston Police Officer John O’Keefe, in late January 2022.

Norfolk prosecutors accuse Read of backing into O’Keefe with her SUV after the pair spent a night out drinking in two Canton bars and then were invited to an after-party at 34 Fairview Road.

Read’s defense has offered a hearty challenge to that narrative and has alleged that fellow Boston cop Brian Albert, who owned that home at the time, as well as Albert’s sister-in-law Jennifer McCabe, are the ones ultimately to blame for O’Keefe’s death and have helped to orchestrate a cover-up. Both Albert and McCabe have retained their own attorneys in the case.

Kearney is a strong defender and promoter of the defense theory and has produced a significant number of writings and videos delving ever deeper into the topic.

It is in these pursuits that prosecutors say that he has harassed and intimidated witnesses and enjoined his followers to do the same. Or, as Mello put it: “He’s hiding behind the guise of a journalist to in fact be an activist.”
