A Davenport man has pleaded not guilty to charges in connection with a 2015 assault that left one man seriously injured at a Davenport strip club.

Trenton Diontre Shelton, 31, waived his right to a formal arraignment and filed his plea via his attorney, Joel Walker, to charges of attempted murder and willful injury resulting in serious injury.

The attempted murder charge, a Class B felony punishable by up to 25 years in prison, was added Tuesday.

He also pleaded not guilty to failure to comply with sex offender registry requirements, an aggravated misdemeanor, in a separate case. 

A bond review is scheduled Feb. 28. Walker filed a motion to a bond reduction Wednesday and wrote that Shelton was unable to post $10,000 cash-only bond.

The same day, Assistant Scott County Attorney Amy Devine filed a resistance to the bond reduction and requested that it be increased to $100,000 cash-only.

She wrote in the motion that Shelton is a flight risk and that the actions he's accused of “caused such extensive and devastating injuries to the victim that he is still in a vegetative state to this day.”

Shelton also is a habitual offender with an extensive criminal history, Devine wrote.

At 12:26 a.m. Oct. 15, 2015, Davenport police officers responded to a fight at Chorus Line, 4128 Brady St.

Police say Shelton and his brothers, Kamden and Juan, were involved in a fight with Joshua Sutton, 41, who was knocked to the floor. According to police, Sutton was kicked in the head and torso several times and stomped on.

Kamden Shelton was arrested the day of the incident. Juan Shelton was arrested the next day after police say he led them on a five-minute car chase from Rock Island into Davenport via the Interstate 280 bridge.

Trenton Shelton was arrested in December 2015 in Mississippi by the U.S. Marshals Service. He was charged in federal court with failing to register as a sex offender, and in November, he was sentenced to 16 months in prison.

He was released from custody and booked into the Scott County Jail on Feb. 8.

Kamden Shelton entered an Alford plea to willful injury causing serious injury and was sentenced the following month to up to 10 years in prison. In an Alford plea, a defendant does not admit guilt but concedes prosecutors have enough evidence to win a conviction.

Juan Shelton also entered an Alford plea in May to willful injury causing serious injury. He pleaded as a habitual offender, which prosecutors can seek if a defendant has two prior felony convictions.

He faced 15 years in prison and was advised at the time of his plea that he must serve at least three years of the sentence before he is eligible for parole. Later that month, he filed a motion to take back the plea, saying he was not properly advised.

His attorney, Russell Dircks, argued Juan Shelton was not properly advised that he must serve half, or 7½ years, of the sentence because he was on parole at the time of the assault.

District Court Judge Thomas Reidel allowed Juan Shelton to take back his plea and reinstated the charges. He has a final pretrial conference March 8.

In October, Juan Shelton filed a federal lawsuit against Davenport police officers Scott Lansing, Gilbert Proehl, Aric Robinson and Dennis Colclasure. Shelton claimed in his suit that the officers used excessive force during his arrest. 

The officers denied the allegation in an answer to the lawsuit that was filed in December.

A federal judge on Tuesday granted his motion to appoint him an attorney to represent him in the suit.
