A 20-year-old Richmond woman has been convicted of robbing and killing a Virginia Commonwealth University student in March.

Zsabriela Williams entered an Alford plea Tuesday on one count of murder, meaning she didn't admit guilt but acknowledged there was enough evidence to convict her in the slaying of 19-year-old Tyler Binsted of Mount Jackson. She also pleaded guilty to two counts of robbery and three of using a firearm in a felony.

Williams and 17-year-old Howard R. Scott III, of Richmond, each face three life terms when they're sentenced on November 17. Scott previously entered Alford pleas to six charges.

Binsted and his girlfriend were robbed March 27 in Byrd Park and ordered to climb into the trunk of her car. Prosecutors say Williams shot Binstead in the back when he tried to walk away.
