Garcia's mother, Cecilia Garcia, told the newspaper that learning that the man suspected of causing a crash that killed her son was a police officer makes things "10 times worse" for her.
"He's supposed to be protecting us," she told the paper.
Joaquin Garcia was studying to be a surgical technician at Malcolm X College in Chicago and was set to graduate in May, according to family members. Torres was a first-year student at DePaul University.
"We were supposed to be going to my brother's graduation in a month," said his sister, who is also named Cecilia. "Now, we're planning his funeral."
Garrett, who has been relieved of his police powers, has been placed on administrative leave from his job in North Chicago.
