Any person who maliciously shoots at, or maliciously throws any missile at or against, any train or cars on any railroad or other transportation company or any vessel or other watercraft, or any motor vehicle or other vehicles when occupied by one or more persons, whereby the life of any person on such train, car, vessel, or other watercraft, or in such motor vehicle or other vehicle, may be put in peril, is guilty of a Class 4 felony. In the event of the death of any such person, resulting from such malicious shooting or throwing, the person so offending is guilty of murder in the second degree. However, if the homicide is willful, deliberate, and premeditated, he is guilty of murder in the first degree.
If any such act is committed unlawfully, but not maliciously, the person so offending is guilty of a Class 6 felony and, in the event of the death of any such person, resulting from such unlawful act, the person so offending is guilty of involuntary manslaughter.
If any person commits a violation of this section by maliciously or unlawfully shooting, with a firearm, at a conspicuously marked law-enforcement, fire, or emergency medical services vehicle, the sentence imposed shall include a mandatory minimum term of imprisonment of one year to be served consecutively with any other sentence.
