Eddie D. Callaway, charged with the alleged shooting death of Shanel "Nani" Negron on April 22, committed suicide in Indiana Tuesday night.
Waukesha police confirmed at a Wednesday afternoon news conference that Callaway, 26, shot himself in the head after he was located on a bicycle by an Indiana state police detective around 10:30 p.m. in Bloomington, Ind.
Other officers responded to search for the suspect before a Bloomington police officer located Callaway on a trail.
When Callaway was ordered off his bicycle and being held on the ground, additional back-up officers were called.
After a back-up officer arrived, Callaway reached toward his waistband and retrieved a weapon despite verbal commands to keep his hands outstretched away from his body, Bloomington police said.
Callaway pulled a gun out of his waistband and shot himself in the head. Callaway was pronounced dead at the scene by medical personnel.
Callaway's death is being investigated by the Bloomington Police Department.
He was on the loose since allegedly shooting to death Negron, a 24-year-old mother, at the corner of Moreland Boulevard and Summit Avenue nine days ago during a domestic dispute, initiating a manhunt involving both local and national law enforcement officials.
Callaway was last seen leaving the scene in a 2002 Ford Taurus, license plate number 394TVK.
"We're glad to bring this case to a closure," said Waukesha Deputy Police Chief Dennis Angle.
Angle said at the news conference that the Waukesha Police Department is confident Callaway is the lone suspect in Negron's death. He said the department is still in the process of completing the investigation, including forensics and ballistics testing.
Negron is survived by her 3-year-old daughter.
"The most tragic part of this incident is knowing that right now we have a 3-year-old who doesn't have a mother anymore and that's completely tragic," Angle said.
Angle said Waukesha utilized its partnerships on the investigation such as the U.S. Marshals and the Milwaukee Police Department.
"One great help was the billboard that was utilized to get Mr. Callaway's picture out so that everyone knew who they were looking for," Angle said. "Obviously, he was very recognizable with the tattoos on his face and I think that really helps."
Callaway had made several trips to Indiana previously to visit relatives. The U.S. Marshals, Indiana State Police and the Bloomington Police Department were looking for the suspect over the last several days, Bloomington police said.
Angle said the Waukesha Police Department believes that Callaway was in that area for the "bulk of the time after the homicide."
Angle added Bloomington police had a general belief of where Callaway was and with increased patrol in that area, it assisted police in locating him.
"But having that distinct face with all that ink really helped," Angle said.
Callaway was allowed to serve probation in Indiana after being convicted of disorderly conduct in 2011. In January 2012, he was arrested for allegedly threatening to stab his girlfriend with a knife and sentenced to a year in prison in Wisconsin for violating parole. The Indiana charges were later dismissed.
Bloomington is about 5.5 hours southeast of Waukesha and an hour south of Indianapolis.
