Jury selection for the Kaitlyn Conley murder trial wrapped up after only one day.

Conley is accused of killing her boss, 60-year-old Mary Yoder, in July 2015. Prosecutors say she poisoned Yoder with colchicine, but the defense claims Conley is innocent. 

Judge Michael Dwyer told the jurors the trial could take up to three weeks with about 60 witnesses expected to testify. 

Assistant District Attorney Laurie Lisi spent a lengthy amount of time talking about the victim's husband and his current romantic relationship with his deceased wife's sister. Lisi says he turned to her during his time of grief. All of the jurors said they could still be impartial knowing that information. 

Opening statements are scheduled to begin Tuesday morning.
