The nuns, who belonged to the Benedictine Sisters of Virginia, were on their way from Richmond to Bristow for an annual retreat. Sister Denise Mosier was killed. Sisters Charlotte Lange and Connie Ruth Lupton, both in their 70s, were badly hurt.

In court Friday, Martinelly-Montano said during his time in jail he has dedicated himself to God and the Bible and hopes to someday become a pastor. The sisters have said they show forgiveness.

“I know this has had an impact on you,” Prince William Circuit Court Judge Lon Edward Farris told Martinelly-Montano. “I know you’ve made changes and great strides, but society has got to be protected.”

Martinelly-Montano, originally from Bolivia, had twice been arrested on drunk driving charges before the crash and federal authorities had scheduled a deportation hearing.

The case prompted calls for stricter immigration enforcement.

Martinelly-Montano also pleaded guilty to five charges stemming from the incident: involuntary manslaughter, two counts of maiming while driving under the influence, driving on a revoked license and a third DUI offense within five years.

The charges carry a maximum of 70 years in prison.
