CHARLES CITY | The state of Iowa continued to present its case on Thursday against Antoine Williams, the 36-year-old Chicago native accused of shooting a Mason City man in Charles City this past June.

Iowa Assistant Attorney General Coleman McAllister and Floyd County Attorney Rachel Ginbey called several witnesses to testify Thursday, ranging from law enforcement officials to the state medical examiner to Williams' neighbors at the Casa Apartments in Charles City.

According to police, Williams shot 36-year-old Nathaniel Fleming, last known address Mason City, multiple times, causing his death. He has been accused of first-degree murder.

The youngest to testify Thursday was Williams' seven-year-old daughter. She stated she looked outside her bedroom window the night of the shooting and saw a body near a dumpster in a parking lot near the Casa Apartments. She didn't, however, know who it was, but did see a red SUV drive off shortly after the fatal shooting.

That red SUV, a Chevy Equinox, was recovered by Waterloo police on July 3, multiple witnesses testified Thursday. Police claim that Williams fled in that vehicle and eventually ended up in Chicago, where he was taken into custody July 5.

Much of Thursday's testimony was dedicated to how multiple police forces worked together to evaluate the crime scene and eventually find Williams in Chicago. Scott Reger, a special agent in the Iowa Division of Criminal Investigations, told the jury he arrived at the crime scene at about 11:30 p.m. the night of the shooting, and interviewed several witnesses who heard what they thought were fireworks.

One of those witnesses was Tracy Hagen, who lived on the first floor of the Casa Apartments and said she knew Williams before the shooting. Hagen stated she was just entering the apartment complex with her family when she heard about six or seven pops.

"We assumed it was fireworks, since it was close to the Fourth of July," Hagen testified.

Another witness who heard the shooting was Chris Geweke-Vierkant, who was living in Highland Terrace Apartments, a nearby apartment complex. Geweke-Vierkant testified that he passed Williams in the Casa Apartment parking lot minutes before the shooting occurred.

He then saw two bright flashes and heard two bangs, which he thought were fireworks. He added that he knew Williams before the shooting, but only had short conversations while bumping into him on the street.

Testimony concerning the shooting Thursday focused on the periods before and after Fleming was shot, but not the incident itself. Dennis Klein, the state medical examiner, did detail the effects of the shooting on Fleming's body to jurors, and stated the cause of death was a homicide.

Klein, who performed the autopsy on Fleming, testified he could not conclude how many times Fleming was shot, because of various entrance and exit wounds on his body. He did, however, add it was either between four and six, and "most likely" five. 

There was extensive injuries to Fleming's neck, Klein testified. These were also shown to jurors through multiple autopsy photographs.

"I'm not a thoracic surgeon, nor am I a vascular surgeon, but I think it would have been a very difficult task to save his life," Klein testified.

Klein added that at the time of his death, Fleming had a blood alcohol level of about .242. No other drugs were found in his system, he said.

The last person who testified Thursday was Michael Roehrkasse, who originally led the investigation of the shooting with the state's Division of Criminal Investigations. He now works with the McHenry County Sheriff's office in Illinois.

Roehrkasse said that he collected evidence and took photos at the crime scene on June 30, which were shown to jurors. He added that he acted on a search warrant on Williams' apartment, which was "very bare." 

No weapons, ammo or other significant pieces of evidence were found there, Roehrkasse said.

Testimony concluded at about 4:30 p.m. Thursday. The trial is scheduled to resume at 9 a.m. tomorrow.
