The man accused of causing the death of a local rap artist in 2019 is out on bond and pleaded not guilty to all charges in a separate attempted homicide case Thursday.

Aee Shawn Mathews, 26, is accused of killing William Underwood, who went by the rapper name “FYL Jackk,” on Sept. 17, 2019. The allegations against Mathews include that local radio personality and rapper Derrick Bernard, 35, ordered Mathews to kill Underwood because of an online feud.

Mathews appeared in court for a virtual hearing after posting an $800,000 surety bond to be released from custody last month, according to court records.

At the hearing, Mathews’ attorney, Josh Tolini, told the court that his client intended to plead not guilty to all charges in both cases he faces.

In addition to the first-degree murder charges for allegedly shooting and killing Underwood, Mathews faces seven charges — including attempted first-degree murder — in a 2022 criminal case.

After brief discussion with Judge Gregory Lammons, Mathews opted only to plead not guilty to all charges stemming from the 2022 attempted homicide case.

Mathews is expected to enter not-guilty pleas in his second case on Aug. 1 to extend his speedy-trial date, which is a defendant’s right to a trial within six months of entering a plea.

Mathews will begin trial on the attempted homicide case on Dec. 2. Attorneys agreed that the trial is expected to last about two weeks.

Bernard, who is representing himself, will face trial before Mathews on Sept. 3 for the beginning of his two trials. Bernard is accused of the attempted homicide of a Colorado Springs police officer in 2020. Bernard is slated to begin his second jury trial on Oct. 8, where he is accused of ordering Mathews to kill Underwood.

At Bernard’s preliminary hearing in May, prosecutors outlined how they believe a feud that started online led to Bernard ordering Mathews to kill Underwood from inside the El Paso County jail, where he was being held at the time on assault charges.

Bernard’s conduct in court throughout his preliminary hearing came under the scrutiny of Lammons. Bernard objected to nearly every piece of evidence presented by the prosecution, and often had verbal and physical reactions — including laughing — to claims being made in testimony.

Bernard on social media and in direct email communication has claimed to be innocent of all charges.

Last month, a Facebook page belonging to Bernard made a lengthy post in which he alleged that he and Mathews are being illegally detained and had nothing to do with Underwood’s death.

“I haven’t been charged with these crimes because there’s any guilt, let alone actual evidence. I’ve been charged in order to discredit the actual truth being told regarding law enforcement and public officials from illegally robbing the hell out of the citizens of ‘Olympic City USA,’” part of the Facebook post uploaded on Tuesday stated.

“Ask yourselves this, ‘If police had enough probable cause to arrest me in 2019, why are they now arresting me five years later, on the eve of a politically charged trial that threatened the careers of countless individuals within El Paso County?’”
