Marks arrived in court just before 9:40 a.m. Friday in shackles and two guards at his side. He seemed calm and collected throughout the arraignment. A clean-shaved Marks even smiled at one point during his 10-minute court appearance.

After the hearing, Channel 6 reporter Jasmin Caldwell spoke with Marks' attorney Michael White who said his relationship with Marks is strained after  Marks hired two private investigators against White's advice.

White said Marks could face up to 99 years in prison for the burglary charge plus a fine up to $10,000. The tampering with evidence charge carries a two to 10-year sentence and a fine up to $10,000.

"We talked about the possibility of the death penalty," White said in regards to the murder charge.

Life in prison is also on the table, White said. He said he should know the state’s plans in a week or two.
