The two men were aware of each other in some capacity, but they were not closely connected.

Yeah, so in this civil lawsuit, she lays out a long list of accusations.

You know, of course, you remember, a lot of people remember, Reed was acquitted earlier this year.

Prosecutors had tried and failed to convince the jury to convict her of murdering O'Keefe by backing her SUV into him.

And now she is suing the investigators that were on the case, along with several people who were inside the Canton home where she says she last saw O'Keefe alive.

Yeah, so it's very similar to what she alleged at her criminal trial, too.

The lawsuit claims O'Keefe got into an altercation at the Canton home.

He suffered a head wound and was attacked by the homeowner's German shepherd.

Reed points to the state medical examiner's autopsy, which did note scratches and what the suit calls dog bite wounds.

So according to the filing, people inside the home moved his body outside to make it look like he had been hit by her SUV and left in the snow.

They have repeatedly denied any involvement in O'Keefe's death.

In fact, they say O'Keefe never entered the home that night, and their attorneys said the allegations are entirely false, defamatory, and without merit.

So the suit accuses all three men of failing to conduct a meaningful investigation into other suspects.

And the lawsuit bashes Proctor's investigation.

When it comes to Proctor's supervisors, the suit accuses them of failing to intervene when they became aware of Proctor's misconduct.

Have we heard any response from them yet?

So all three men have denied any conspiracy in the past or undermining the investigation.

NBC has yet to receive any comment from Proctor and Sergeant Buchanek about the lawsuit in particular.

But an attorney for Lieutenant Brian Tolley said he was looking forward to a civil trial and, quote, was never part of any so-called conspiracy and cover-up.

So what authorities have said so far is that the suspect is 27-year-old Cedric Irving Jr.
