At first, the police could not identify some of the chemicals, Detective Samuel said.

The police do not know what prompted the attack, Detective Samuel said.

But they shot two employees and one customer, Detective Samuel said.

The woman was treated at a local hospital and released, Detective Samuel said.

The accident was still under investigation last night, Detective Samuel said.

"We only respond to questions about the police department," Detective Samuel said.

He then raped the woman and left, Detective Samuel said.

As of early this morning, little else was known about the circumstances surrounding the case, Detective Samuel said.

Detective Samuel said that adults were home at the time of the accident, but not in the same room as the boy.

Detective Samuel would not say whether the officer was wearing a bulletproof vest.
