Davenport police have arrested two people in connection with the Sept. 22 shooting death of 20-year-old Brady Tumlinson during a robbery at the victim’s home.

Tristin Antonio Joseph Alderman, 22, of Davenport, and Nakita Ronschel Wiseman Jr., 21, of Bettendorf, are charged with one count each of first-degree murder, first-degree robbery and conspiracy to commit a forcible felony.

First-degree murder carries an automatic sentence of life in prison upon conviction under Iowa law. First-degree robbery is a Class B felony that carries an automatic prison sentence of 25 years, 17½ of which must be served before parole can be granted. Conspiracy to commit a forcible felony is a Class C felony that carries a prison sentence of up to 10 years.

Alderman was taken into custody Friday at the Iowa Department of Corrections, 605 Main St., where he was serving a term on work release after being paroled from the Iowa Department of Corrections on Aug. 18 on convictions of second-degree burglary and willful injury causing bodily injury in a case dating back to 2013.

Wiseman was taken into custody from 3765 Creek Hill, Apt. 2, Bettendorf.

Both men were being held Friday night without bond in the Scott County Jail.

According to the arrest affidavits filed by Davenport Police Cpl. Bryon Grothus, Alderman, Wiseman and three other accomplices had conspired to rob Tumlinson at 1321 S. Nevada Ave.

Once they were all at the residence, one of the accomplices told police that Alderman pointed at a window and told the other accomplices it was the bedroom.

Alderman entered the residence and was present inside the home when the shooting began. Alderman fled from the opposite side of the house from where the group had entered.

Surveillance video near the victim’s home shows five people running away from the direction of the victim’s home.

Immediately after the shooting, witnesses identified Alderman as being with Wiseman, according to the arrest affidavits.

Inside the residence, Tumlinson died of his wounds, and a woman was seriously wounded. The woman continues to recover from her wounds. 

The morning of the shooting, police were called to the scene at 7:34 a.m. A neighbor had heard the woman’s screams for help and when he went into the home the woman told him they had been shot. The neighbor then called police.

Alderman returned to the scene the next morning as police were investigating. He took police to a set of bloody gloves nearby.

The gloves contained the DNA of one of the accomplices, according to Grothus’ affidavits. During an interview with police the accomplice stated he had been shot during the incident.

Davenport police said the investigation is ongoing and more arrests are possible.
