Hudson is charged with first-degree murder in the Friday morning death of his ex-wife, Melissa Bridgewater, 45.
Police say she was killed execution style in the parking lot of the hotel.
A visitation service for Bridgewater is scheduled for Wednesday afternoon in Maywood.
In court Wednesday, DuPage County State's Attorney Joe Birkett described Bridgewater's murder as cold, calculated and premeditated. He revealed that she was so afraid of her ex-husband that on the morning she was shot, she asked an escort to walk her to her car. But it wasn't enough.
Bridgewater and Hudson had been married for 18 years but got divorced in 2006. And prosecutors say Bridgewater's ex-husband had threatened to kill her.
"The abuser is contemplating his conduct, planning for that moment when she is going to explode," said Birkett.
Birkett said Hudson left a note December 30 at his Bolingbrook home that he called a suicide note.
"Melissa has taken my manhood so I'm taking her with me," the note said according to Birkett. "I can't leave this earth knowing she used me for 20 years. Please forgive me. I don't need to suffer anymore."
"He's guilty of capital murder. And he killed her, and previously planned to take her life," said Birkett.
The courtroom was filled with family members in support of Hudson. After the judge denied bond, distraught family members said very little.
Hudson's defense attorney said his client is distraught as well and that he loved his ex-wife and is grieving just like the other family members. He pointed to the fact that Hudson turned himself in to police Tuesday night and has been cooperating with police.
