A 43-year-old Illinois man is wanted for murder in South Bend and now faces several additional charges in what looks like a crime spree.

Police say Anthony "Bones" Jefferson of Carol, Stream, Ill. is the suspect in an early Monday morning shooting that left one man dead and another seriously injured.

Jason Reid, 34, of Indianapolis was killed, and Tyreece Walker, 33, of South Bend was the man injured.

Shortly after 5 a.m. Monday, South Bend police were called to the area of Fassnacht Ave. and Brookfield St. on a report of shots fired. A short time later, officers received a 911 call from a woman who lives at a home in the 1800 block of Fassnacht and found Walker. Walker pointed police to a home across the street. Officers performed a sweep of the Brookfield St. home where they found Reid's body.

The exact motive was unclear.

Jefferson is considered armed and dangerous.

The St. Joseph County prosecutor's office late Wednesday afternoon said the state has filed additional charges -- two counts of robbery and two counts of confinement.

Jefferson was originally charged with murder and attempted murder for the shootings of Reid and Walker.

He's also accused of forcing a woman to withdraw $200 from an ATM on Sunday as she was checking her bank balance. The ATM is in the 5600 block of N. Main St. in Mishawaka. Jefferson then allegedly forced the woman to drive him to another location where it appears he took her cellphone.

On Monday, investigators also believe Jefferson approached a cashier at the 7-Eleven at Logan and Jefferson in South Bend and is accused of throwing coffee in the cashier's face. The prosecutor's office says at that point, Jefferson allegedly asked the cashier to open the registers, taking cash and cigarettes.

Authorities believe Jefferson is driving a white 2001 Mitsubishi Eclipse with an Illinois license plate of 2953BH.

The U.S. Marshal's Service Task Force and other police agencies are actively looking for him.
