Riverside police arrested three men Saturday who were allegedly selling cocaine and other drugs out of a second-floor apartment in the 400 block of Northgate Court.

Police searched the apartment at 472 Northgate Court at 3 a.m. Saturday and found 14 grams of cocaine package for sale, anabolic steroids, human growth hormones and cash, police said. Officers from the Riverside Police Department and the West Suburban Directed Gang Enforcement Task Force — also know as WEDGE — had been observing the apartment for several weeks.

“We’d known about (the illegal activity) for the last three to four weeks,” Assistant Chief Thomas Weitzel said. “We passed the information along to WEDGE and they’ve been working the case.”

A Riverside patrol officer stopped a car that pulled away from the apartment about 6 p.m. Friday for having windows that were too darkly tinted. During the stop, the officer found 127 grams of cocaine packaged in several plastic bags, police said. The driver, Robert Marquez, 24, of 4917 W. 31st Street in Cicero, was arrested.

After questioning Marquez, police obtained a search warrant for the apartment, where David Erickson, 34, and Keith D. Hovorka Jr., 25, were arrested. The cocaine in the apartment was in Hovorka’s possession and the steroids and human growth hormones were in Erickson’s, Weitzel said.

Marquez was charged with possession of a controlled substance and possession of a controlled substance with intent to deliver, a Class X felony. Hovorka was charged with possession of a controlled substance, and manufacture and delivery of a controlled substance. The men both appeared Monday in Cook County Circuit Court in Maywood and were given September court dates. Bond was set at $75,000 for Hovorka and $1 million for Marquez.

“These (charges) could be upgraded to super Class X felonies because both Hovorka and Marquez are self-admitted gang members and they have extensive criminal histories,” Weitzel said.

Erickson was charged with possession of anabolic steroids, a misdemeanor.

“He said (the steroids) were for personal use, but paraphernalia found in the apartment suggests otherwise,” Weitzel said. “There could be additional charges filed later.”

Police found electronic scales and packaging equipment in the apartment. Weitzel said this is the first case in his career with the Riverside Police Department in which he has encountered steroids and human growth hormones as a part of a criminal offense.
