Police arrested Glen Richter, 49, for the recent college graduate’s death. He was booked into Lew Sterrett Jail early Thursday morning on a capital murder charge.

According to the arrest warrant, surveillance video showed Hudson getting out of her SUV before Richter approached her, then forced her back into the vehicle. Police were able to gather fingerprints from two of the vehicle’s doors, which led them to Richter.

Police sources said Hudson was carjacked at gunpoint and forced to an ATM by Richter. Hudson’s body was partially clothed when she was found, leading police to say Richter sexually assaulted her.

We wish to express our sincere gratitude to all who have so lovingly surrounded us at this time of loss and sadness. The thoughts and prayers of so many have touched us more than we can ever express.

We have the utmost trust and confidence in the Dallas County District Attorney’s Office.

At this time, we will focus on healing, the grief we have, and living with this senseless tragedy.
