Drew Carter III was convicted in June for the 2019 shooting death of his ex-girlfriend, Jessica Flores.
Her body was found in a wooded area in Gary.
The 36-year-old was a mother of six.
Lake County, Indiana prosecutors confirm the judge handed down sentences Wednesday totaling 101 years behind bars.
Carter's conviction came after a judge granted a motion to dismiss the murder case against him in September 2019. He remained in custody on a separate firearms charge stemming from his arrest, and prosecutors refiled murder charges in October 2022.
But Carter was released on bond in 2023 because, under Indiana law, if a case isn't brought to trial within 180 days, the defendant has a right to be released while they wait.
