The cause and manner of death has not been determined, but both victims had gunshot wounds, the coroner’s office said.
Springfield Police Division Lt. Lou Turner said Monday night’s double homicide and the one from Sunday are not related.
Turner said detectives are “acting on several leads,” in Monday’s case.
“There were several people in the house that are being interviewed,” Turner said.

Police are also investigating a robbery that took place hours before Mincer and Brown were found dead. Officers were dispatched around 12:45 p.m. to Springfield Regional Medical Center in reference to a robbery incident that took place at a Clifton Avenue home, according to a Springfield police report.
When police arrived, they spoke with the victim who said, “that he lost his job and admitted that he’s been selling marijuana to make money.”
The victim told officers he talked to his friend, Mincer, about buying some marijuana, the report said. The victim then went to meet Mincer at the Clifton Avenue home.
The victim said that while he was inside the upstairs half of the double, “someone grabbed him from behind and put him into a headlock. (The victim) stated another male came out with a semi-automatic handgun and told him that if he moved he would blow his brains out,” the report said.
The three then kicked the victim out of the house before stealing his marijuana and money, the report said.
The victim told officers he believes the male who put him in a headlock was Colin Michael, and the male who had the gun was Brown.
In Sunday’s homicide, a 28-year-old woman was found with a gunshot wound to the head around 7:30 a.m. in the area of 1429 S. Fountain Ave., Turner said.
The woman was identified as Kirstie Lally, Turner said.
Turner said detectives are also following several leads in Lally’s case, but do not have a suspect yet.
Springfield detectives on the scene Sunday interviewed a passerby that found Lally, according to the report.
“(Witness) advised that she came out of the house in the area and observed the female laying on the sidewalk,” the report said. “When she got close to the female, she could tell that the female was unresponsive and contacted police.”
Turner said anyone with information on Lally’s death is encouraged to call the division’s non-emergency number at 937-324-7716.

Lally was the first homicide in the city of Springfield in 2020 —with Mincer and Brown that number has quickly jumped to three. In 2019, the city had four homicides.
In 2018, the city had 13 slayings.
“All loss of life is tragic,” Springfield City Manager Bryan Heck said.
“One homicide would be one too many in this community,” Heck said. “Investigators with the Springfield Police Division are actively investigating both incidents and the City of Springfield as a whole maintains zero tolerance for this senseless violence.”
Turner said it’s “been rough,” for the division with back-to-back homicides.
“The detectives are doing a great job. They aren’t getting a lot of sleep. They are doing more than their share,” Turner said. “But we are all doing what we have to do.”
