SAUGANASH — No one has been arrested in connection with the death of a 17-year-old Sauganash teen who was fatally shot in a Norwood Park restaurant parking lot one month ago, officials said Wednesday.

The investigation into Anthony Heatherly's death is ongoing, according to a statement from Chicago Police Department officials.

The teen, a former Taft High School student who was enrolled in an alternative high school and lived in Sauganash, met someone around 1 p.m. April 4 in the parking lot behind the Taco Burrito King, 5509 N. Harlem Ave., when an argument ended in gunfire and the theft of the victim's car, according to a source close to the investigation.

A bag of marijuana reportedly was found next to the teen when police and paramedics arrived.

Police do not believe the teen was involved in a gang, sources say.

Ald. Anthony Napolitano (41st) said he asks officers for an update every day on the search for the teen's killer.

Napolitano said he was confident that the Chicago Police detectives were doing everything possible to find Anthony's killer, but worries that the Jefferson Park Police District does not have enough officers to handle the investigation.

The incident prompted Napolitano to renew his call for more officers to be assigned to the Far Northwest Side, which is the largest — and by many measures, safest — police district in the city.

Anthony's death was the second shooting in Norwood Park since July 2013, according to data complied by DNAinfo.

Napolitano, who was a police officer and firefighter for 10 years before being elected alderman a year ago, said police may not want to release information about the investigation for fear of jeopardizing the court case.

"I am sure they are working on it," Napolitano said.

Marilyn Falkenberg, a teacher at Taft, remembered Anthony as a "nice kid."

"He was not the most motivated of students, but he was bright and funny and capable," Falkenberg said.

Anthony also was mourned by members of the Chicagoland Petrolheads and Car Spotters group on Facebook, which was devoted to car lovers.

The teen's family Wednesday declined to speak to a reporter from DNAinfo.
