CEDAR RAPIDS — A man wanted for murder shortly after the attack at a downtown nightclub this month was tracked down by federal marshals to a Chicago suburb and was arrested Monday, bringing to two men detained in the shooting that killed two and injured 10.
Dimione Jamal Walker, 29, was arrested by the U.S. Marshals Service in Matteson, Ill. He faces charges in Linn County of first-degree murder, intimidation with a dangerous weapon, going armed with intent and felon in possession of a firearm. He was also wanted by the Illinois Department of Corrections on a charge of parole violation — possession of a weapon.
A news release from the U.S. Marshals says that Cedar Rapids police on April 11 — the day after the shooting in the Taboo Nightclub and Lounge — contacted the Northern Iowa Fugitive Task Force asking for help apprehending Walker.
Task force officers determined by April 12 that Walker had fled the state, so they began coordinating with the U.S. Marshals. On April 14, marshals received information Walker was likely in the Chicago area, and they began coordinating with the Great Lakes Regional Fugitive Task Force.
Officers with the Great Lakes Task Force arrested Walker shortly after 10 a.m. Monday as he left a building in the 500 block of Holiday Plaza Drive in Matteson. He was in custody Monday afternoon of the Chicago police.
A criminal complaint against Walker, which would amplify the charges against him, hasn’t been filed yet in court.
The other suspect in the case, Timothy L. Rush, 32, is in jail on charges that include a second-degree murder charge that he killed Nicole Owens, 35. Michael Valentine, 25, also was killed in the attack. Authorities would not confirm if they believe Walker is responsible for that murder, or say why he faces a first-degree murder charge while the other suspected gunman faces a second-degree murder charge.
The Linn County Sheriff’s Office is coordinating with the U.S. Marshals and the Illinois Department of Corrections to return Walker to Linn County. Linn County will request that his return here be expedited despite the Illinois charges, according to a news release from the county.
Walker, who served time in an Iowa prison, has a criminal history in both Iowa and Illinois, starting with juvenile cases in Johnson County involving theft and drugs, which were filed between 2006 and 2010. He also had several adult cases in Johnson County involving theft and drugs starting in 2011. Some of the cases were dismissed, and Walker pleaded guilty to other cases and was sentenced to probation for them.
In 2015, Walker was charged with operating a car without the owner’s consent, false imprisonment and assault after he and a friend forced a woman into the back seat of her own car, according to a criminal complaint. The victim had agreed to give Walker and his friend a ride as far as Swisher from Cedar Rapids. At the Swisher exit, Walker slammed the car into park and stole the keys.
Walker pleaded guilty in that case and was sentenced to 60 days in the Johnson County Jail.
In 2017, he was involved in two more criminal cases. In the first, he originally was charged with willful injury, assault with intent to inflict serious injury and participating in a riot. In the second, he was charged with first-degree harassment, carrying weapons, assault while displaying a dangerous weapon, fourth-degree theft and going armed with intent. All of those charges were dropped as part of a plea deal in which he pleaded guilty to trafficking a stolen weapon used in a crime.
In the first of the two 2017 cases, Walker was accused of being part of a group of several people who jumped a person. One member of the attacking group pulled out a gun and shot at the victim, but police were unable to determine who shot the gun, according to a warrant request filed in the case.
In the second 2017 case, Walker reportedly got into a fight with a woman, and when she got in her car to leave, he blocked her path and pointed a gun at her. The woman, who was afraid Walker would shoot her, hit him with her car as she drove away, according to a warrant request.
Walker was sentenced in 2018 to five years in prison, with credit for the time he had already served in jail during the court process. The Iowa Department of Corrections website indicates Walker was released from prison in September 2019. and was out on work release at the time of his arrest Monday.
