LANSING, Mich. (AP) -- UPDATE: A 99-year-old RV driver who went the wrong way on a Florida highway and killed two teenagers in a head-on crash has died of his injuries.
The Florida Highway Patrol said Monday that Walter Roney of Dearborn, Michigan, died on Friday.
His death came three days after the Fort Pierce crash that killed 18-year-old Santia Feketa and her 17-year-old best friend, Britney Poindexter.
The teens were headed to a skating rink.
Michigan driving records showed that someone in September had reported Roney as possibly incompetent to drive, but 29 days before the crash he had passed a driving test in his home state.
Investigators say Roney was driving at night without lights going west in the eastbound lanes of a four-lane highway when he crashed into Feketa's pickup truck.
The Michigan Secretary of State's Office gave more information Friday about a re-examination Walter Roney passed Jan. 8, four months after someone asked motor vehicle officials to determine if he was still competent to drive.
The Tuesday night crash in Fort Pierce, Florida, killed best friends Santia Feketa and Britney Poindexter.
The Michigan Secretary of State's Office said Thursday that Roney, of Dearborn, Michigan, had an acceptable medical condition.
On Friday, it said he had favorable statements from two medical professionals and had cleared three tests.
