Four defendants in this year’s so-called “chemical bomb” case, in which five suspects allegedly injured an officer with a homemade explosive, waived their preliminary hearing on July 12.
The suspects, an unidentified juvenile and four 19-year-olds — Gavin Dawson, Braiden Ulmer, Isaac Koch and Maxwell McCann — were arrested April 6 and 7 for their suspected involvement in the attack. They face several charges, including assault and possession of an explosive.
On the morning of April 6, at roughly 12:30 a.m., police received a call about a traffic obstruction where W. 68th Avenue turns into Beech Street.
Officer T. Grahn went to the scene, where he was joined by an individual who had called the department, according to the arrest affidavit. Grahn found several traffic signs in a pile on the street and saran wrap creating a barricade across the road.
As Grahn attempted to remove the signs from the road, an individual in a nearby field threw a plastic bottle at Grahn, which was later found to contain brake fluid and pool cleaner, the affidavit said.
The plastic bottle began to release white smoke, and Grahn fainted minutes later. Grahn was taken to a hospital and “diagnosed with sustaining a chlorine gas exposure,” the affidavit said.
Detectives searched the field the next morning, finding a Walmart receipt listing saran wrap, brake fluid and pool cleaner, the affidavit said. Police checked security footage from the nearby Walmart and made the five arrests after the footage showed the suspects purchasing the items.
In interviews with police, Dawson said the group had “set the smoke bombs off in `random places,’” the affidavit said.
Detectives said that when they interviewed McCann, he told them that “from his reading on the internet he felt the gas from the bombs was not very toxic or harmful,” according to the affidavit.
The arraignment for the four adult suspects will be Sept. 16 at 8:30 a.m.
