Faking Suicide

Samuel Israel III is missing. He may have jumped off a bridge or faked his own suicide. His car was found on the bridge, keys still inside. He wrote “suicide is painless” on the windshield. He left a bottle of pills in the car. This is complete overkill. I think the removal of any two of these four clues would have more convincing. For example; car not on bridge,nothing scrawled on windshield, but keys in car and bottle of pills in glovebox.
