BOSTON (CBS) – Steven Davis doesn’t believe Catherine Greig should be let out on bail, and he is preparing to share his feelings in federal court.

“I’m not a praying man, but I just hope she doesn’t walk and get bail,” said Davis.

Davis said his sister Debbie was killed and dismembered by Whitey Bulger when he was 26 years old. He has been waiting for years for justice and answers, and believes Greig will be more helpful to police behind bars, than out.

“With her being in custody, there will be more dirt brought out about the brothers. And I hope that justice is served with all of them,” said Davis.

WBZ-TV’s Jim Armstrong reports.

Davis said he is still stunned by the arsenal of weapons found in Whitey and Greig’s California home, and the surveillance video of Greig.

“By he way she was walking free and clear through the pharmacy and all the IDs. She knew what she was doing,” said Davis.

To those who sympathize with Greig, Davis asks they put themselves in the shoes of victims families.

“My sister played the ultimate price for the scumbags she associated with. Greig should be accountable too,” said Davis.

Tommy Donahue agrees with Davis. He hasn’t missed a day of court and he’ll be there Wednesday morning, when he hopes a judge will allow him to speak against setting Greig free on bail.

Donahue’s father, Michael, was allegedly gunned down by Whitey Bulger in 1982 as an innocent bystander to Bulger’s rage. Greig, he said, has to answer for her role in protecting Bulger.

Greig is due in court on Wednesday. There may not be a ruling on bail, as the judge can take it under advisement rather than rule from the bench.
