Tsarnaev Defense Expected to Rest

The death penalty trial of Boston Marathon bomber Dzhokhar Tsarnaev is on track to go to the jury by the end of the week or early next week.
The defense, which has called more than 40 witnesses in its bid to persuade jurors to spare Tsarnaev's life, is expected to rest later Monday. Prosecutors are expected to call a witness or two in rebuttal before both sides deliver their closing arguments.
Transcripts of hearings to which the jury wasn't privy indicate the defense plans to call as its final witness Sister Helen Prejean, a Roman Catholic nun made famous by the 1995 movie based on her book "Dead Man Walking."
Prosecutors are fighting to keep her off the witness stand or limit her testimony. Attorneys have not disclosed what she might say or whether she has met with Tsarnaev.
