Jurors in the Robert Pickton trial have heard the accused tell police he got "sloppy" cleaning up, near the end of an 11-hour interrogation as police grilled him about DNA and body parts found on his farm.

Pickton also tells RCMP Staff Sgt. Don Adam that his brother Dave never noticed because he was busy.

The accused makes another apparent admission about nine hours into the interview, recorded on February 2002.

Adam -- one of several officers taking turns questioning Pickton - tells Pickton that police believe women may have been killed in three different areas on his property, including a motorhome.

When asked how many were killed there, Pickton says "probably two, maybe three."

And when Adam asks how many women in total he thinks he's killed, Pickton responds: "You're making me more of a mass killer than I am."

Those comments differ from what jurors heard on Tuesday, when they watched the first few hours of his interrogation video and Pickton dismissed any connection between himself and the missing women as "hogwash."

Pickton is charged with 26 counts of first-degree murder. He is on trial in B.C. Supreme Court in New Westminster, B.C. right now on six counts.

At another point in the video aired Thursday, Adam points at images of 48 missing women and asks Pickton to "touch the ones you've done."

He also tells Pickton that a former friend, Lynn Ellingsen, has told police she saw him skinning the body of a slain woman, and that investigators knew Ellingsen was blackmailing him.

Adam also says that people claim to have seen Pickton sexually assaulting dead women.

"Yeah, right," Pickton laughs.

But when Adam says investigators have collected a large amount of evidence on the farm, Pickton again appears to make an admission, saying: "I made my own grave."

Adam suggests that Pickton hated prostitutes because they attacked him with a knife, stole from him, and infected him with Hepatitis C. The judge told jurors not to consider Adam's statements as evidence.

RCMP Staff Sgt. Bill Fordy is the first officer seen to interrogate Pickton on the video, trying to relate to the accused before switching to a more aggressive tone.

At one point, Fordy says Pickton's DNA was found along with the DNA of Mona Wilson, one of the women he is charged with killing.

"Your DNA is with hers. You're done, done, done. Done like dinner -- like roast pork," he says, adding that investigators found large amounts of Wilson's blood.

Pickton responds: "But that don't mean I did it. I didn't do anything, I don't know her ... I don't know her face or anything else."

Besides Wilson, Pickton is on trial for the deaths of Sereena Abotsway, Marnie Frey, Georgina Papin, Andrea Joesbury and Brenda Wolfe.

On the interrogation video, Pickton admits to owning a .22-calibre weapon and said he used the gun to kill pigs.

A few times, the accused says he shouldn't be talking and that he wants to return to his cell.

But Fordy reminds Pickton that while he doesn't have to say anything, the officer is duty-bound to ask questions.

After one intense period, Pickton says: "I'm sorry. I'm sorry for living. And ah, you know, if I can, I'll take my life for any one of those people just to, just to have them alive. So ... sorry."

In its opening statement on Monday, Crown counsel told the jury that Pickton made incriminating remarks during the 11-hour police interview after he was arrested in February 2002.
