Chicago police officer Robert Rialmo is suing the estate of the 19-year-old he allegedly shot and killed in December.
Rialmo was involved in the December 26 fatal police shootings of Quintonio LeGrier, 19, and his neighbor Bettie Jones, 55.
The officer's lawsuit, filed Friday, claims LeGrier swung a baseball bat at him twice and refused orders to drop it.
According to the lawsuit, LeGrier held "the baseball bat cocked back over his right shoulder with a two-handed grip, approximately 3 feet above Officer Rialmo and approximately 3 to 4 feet from where Officer Rialmo was standing on the bottom step of the front porch to the building. Officer Rialmo feared that LeGrier would strike him in the head with the baseball bat so hard that it would kill him.
"Rialmo reasonably believed that if he did not use deadly force against LeGrier, that LeGrier would kill him. Officer Rialmo drew his handgun from its holster, and starting to fire from holster level, fired eight rounds at LeGrier from his 9 mm Smith & Wesson handgun, which holds 18 rounds, in approximately two and a half seconds," the lawsuit reads.
Jones was, "unbeknownst to Officer Rialmo," standing in the building's front doorway behind LeGrier when shots were fired, according to the lawsuit.
The "fourth round that Officer Rialmo fired passed through LeGrier and struck Bettie Jones," the lawsuit adds.
"The fact that LeGrier's actions ... forced Officer Rialmo to end LeGrier's life, and to accidentally take the innocent life of Bettie Jones, has caused, and will continue to cause, Officer Rialmo to suffer extreme emotional trauma," the lawsuit reads.
Lawsuits filed by the families of LeGrier and Jones provide a different version of events than what is laid out in Rialmo's lawsuit.
