A Bolivian man charged with killing a nun in a car crash in Virginia had at least two previous drunken driving convictions and had been released twice by immigration officers who took him into custody because he was in the United States illegally.

Carlos A. Martinelly Montano, 23, was charged in Sunday's accident in Virginia's Prince William County. Sister Denise Mosier, a nun with the Benedictine Sisters of Virginia, died in the crash, and two others, Sisters Charlotte Lange and Connie Ruth Lupton, were injured. They remained in critical condition on Wednesday, a spokeswoman, Sister Glenna Smith, wrote in an e-mail.

A wake for Mosier was planned for Thursday evening and a funeral Mass and burial for Friday, both at the nuns' Bristow, Va., monastery, according to its website.

The accident occurred as the nation has become divided over how much authority police should have to check the immigration status of people they stop. Some in Virginia would like to expand that authority, similar to a tough law Arizona recently passed. That law is under review in federal court.

In a statement on their website, the nuns said they're upset that the tragedy is being politicized and "become an apparent forum for the illegal immigration agenda."
