The York County Coroner's office said an autopsy Monday morning at Allentown's Lehigh Valley Hospital determined Miller died of multiple injuries.
Police say they have charged an illegal immigrant with homicide by vehicle in Saturday's deadly crash in West Manheim Township.
Around 5:45 a.m. Saturday, West Manheim Township Police investigated the two-vehicle crash on Baltimore Pike near Garrett Road, according to a news release.
The release says a 1995 Ford Windstar, driven by Juan Carlos Bastida-Martinez, 25, of Mexico, was heading south and crossed over the center lines before striking a 2010 Victory Motorcycle, driven by Steven Miller, 64, of Westminster, Md.
Miller sustained fatal injuries at the scene, and the Windstar was engulfed in fire, the release states.
After receiving medical treatment for moderate injuries, Bastida-Martinez was arrested and charged with homicide by vehicle; accidents involving death while not properly licensed; driving while operating privileges were suspended; driving without a valid driver's license; reckless driving; careless driving causing death; and failure to drive on the right side of the road.
Bastida-Martinez said during police interviews that he was illegally living in the United States, and in describing how the crash occurred, he said he "blinked for three seconds" before the impact, charging documents state.
He was taken to Central Booking for arraignment and denied bail, the release states.
