A Cook County judge set bail this morning at $750,000 for the Evanston teen accused of killing 21-year-old Cardereon Preister.

Matthew Dubose, 18, shot and killed Preister about 11 p.m. Sept. 10 while Preister was standing outside his home in the 1700 block of Leland Avenue, according to prosecutors. They say Dubose shot Preister once in the chest from about 10 feet away.

In court this morning, prosecutors said Preister did “rip off” two people earlier this summer, and the fatal shooting was in retaliation for those incidents. Evanston Police Cmdr. Jay Parrott said Thursday that Preister tried to trade his gun for money and drugs, and the deal “went awry.”

Deborah Cohen, Dubose’s attorney, told Judge Marguerite Anne Quinn there is “no evidence at all” that her client killed Preister, including witness statements and a weapon recovery. A prosecutor clarified Dubose was identified by witnesses.

Cohen said Dubose is an Evanston Township High School graduate who works for a church in the city and lives with his parents. His family was in court this morning.

Appearing before Quinn, Dubose spoke only to say his name.

He is scheduled to appear in court again Oct. 16.
