A judge said he'll decide on July 28 what evidence and testimony will be allowed in the murder trial of Angelika Graswald. She's accused of tampering with her fiancé’s kayak last year, causing him to drown. Reporter Steve Brennan was there as a pre-trial hearing wrapped up.

Trying to paint investigators as relentless, defense attorney Richard Portale grilled State Police investigator Donald DeQuarto Tuesday about his interrogation of Angelika Graswald.

Portale asked at one point about the questioning when Graswald was allowed to use the restroom. She came back upset and said she believed she had a miscarriage.

Graswald was questioned for 11 hours, during which time prosecutors said she admitted to killing her fiancé, Vincent Viafore.

Portale also raised questions about whether Graswald understood her Miranda rights. Portale said in the interrogation video it shows Graswald asking, "Who is Miranda?"

Susan McCardell, a volunteer on Bannerman Island, was the final witness was called by the defense. She was there when Graswald met with police while Viafore was still missing. She said she checked on Grawald on three occasions. McCardell testified that State Police were "bullying" Graswald.

Prosecutor Julie Mohl then cross-examined and asked if Graswald ever asked for help or for McCardell to save her. Graswald answered no.

She also testified she was there when Graswald called State Police before leaving for the island to ask if they were still going to meet her there.

Graswald is charged with second-degree murder and is being held on $3 million bail.
