A teenager was killed and two others injured early Friday when a car slammed into a historic East Dundee building, a crash that involved alcohol, authorities said.

Roman Pokorny, 16, who was in the front passenger seat, was pronounced dead at Sherman Hospital, Elgin, around 5:30 a.m., according to Kane County Coroner Charles West.

The driver, Brian Poliarny, 18, of Elgin was charged with driving under the influence of alcohol and other traffic counts, authorities said.

"I don't know where ... they were coming from," said East Dundee Police Chief Terry Mee, who declined to say whether Poliarny's blood-alcohol content was known.

The Kane County state's attorney's office was reviewing the death, said Mee.

The 1994 Mazda was traveling north on Elgin Avenue when it crossed a T-intersection around 4:20 a.m. and smashed into the 135-year-old Haeger Potteries building at 7 Maiden Lane, police said. The car hit the building's cement foundation, which was not damaged, said a Haeger official.

Poliarny of the 1000 block of Biltmore Drive, broke both ankles and Toni Szymanowski, 18, of East Dundee, who was in the back seat, suffered a broken leg, according to officials at Dundee-Crown High School in Carpentersville, who said police briefed them.

Pokorny was a junior at the school, said Basilio Salazar, assistant principal. Students there were very upset, he said.

When Pokorny's father went to sleep Thursday night, he believed the boy was in his room, according to a family member who answered the phone at their home Friday afternoon.

Relatives who visited the crash scene said they could not find any evidence the driver tried to stop before the collision, said the family member.

A Tribune investigation last year found that speeding was the leading contributor to fatal accidents involving teenage drivers. Alcohol was a factor in fewer than 25 percent of the crashes. Many of the deaths may have been prevented with seat belts.

It did not appear that Pokorny was wearing a seat belt, said Mee.

"He had a lot of friends," Salazar said of Pokorny. "Students who were in his Spanish class made a poster using their handprints, and the guidance staff is helping a lot of the kids."

Poliarny is a former student but did not graduate from Dundee-Crown, Salazar said.

A room next to the library was set aside for students to leave notes and other mementos.

Kyle Weelmaa, 16, who said he had known Pokorny since 6th grade, left the dead youth's home Friday afternoon in tears.

"He respected students and teachers," Weelmaa said. "If someone had a problem, he would try to help them."
