An accused husband killer has taken the stand in her own defense.

Amber Hilberling is accused of pushing her now-deceased husband Josh to his death out the window of the 25th floor apartment the couple shared.

Hilberling took the stand late Friday morning to defend herself against a second degree murder charge.

Amber testified that scratches on her shoulder that Tulsa Police detectives took pictures of the day of Josh Hilberling's death were inflicted by Josh.

Defense attorneys also pressed forward with their theory that dangerously thin glass at the apartment is to blame for Josh's death.

Late Thursday afternoon, the prosecution rested its case after prosecutors showed an hour-long video of Amber Hilberling and her grandmother in a police interview room waiting to be questioned by detectives.

In the video, Amber can be heard saying things like, "I killed him" and "I feel so guilty."

Amber's grandmother is heard coaching Amber about what not to say. The grandmother repeatedly instructs Amber to refuse to answer questions until a lawyer arrives to represent her.

Late Thursday, the judge told jurors to anticipate beginning their deliberations on Monday.

Hilberling rejected a plea deal offered by prosecutors last Friday. She faces 10 years to life in prison if convicted of second-degree murder.
