A tip prompted Milwaukee police to check a residence near Greenfield Avenue and 32nd Street, where Borges tried to hide inside a residence, according to a news release from Sparta Deputy Police Chief Booker Ferguson.
Police arrested Borges after about 30 minutes — and before a SWAT team arrived, Ferguson’s release said.
Sparta police investigators were notified of the incident and traveled to Milwaukee, where they conducted search warrants and additional interviews, along with the Wisconsin Department of Justice Division of Criminal Investigation and Milwaukee police.
Borges, who is being held without bond in the Milwaukee County Jail, could face several charges. Monroe County District Attorney Kevin Croninger is expected to file charges of being party a crime of felony murder-armed robbery and distribution of methamphetamine.
Previously charged in the slaying are:
Michael Hartmann, 38, of Milwaukee, who was arrested in Butler, Wis. He faces charges of first-degree intentional homicide, being party to a crime of felony murder-armed robbery and distribution of methamphetamine.
Damara Skenandore-Medina, 28, of Milwaukee, where she was arrested. She is charged with felony murder, armed robbery, distribution of more than 50 grams of methamphetamine and harboring or aiding a felon.
The slaying was an isolated incident that investigators believe was related to the sale of illegal drugs.
The Sparta Police Department is confident that all of the occupants of the vehicle that traveled to Sparta on June 11 to rob the 61-year-old Sparta man are in custody. However, the department continues to investigate, and other arrests are possible, Ferguson said.
