WASHINGTON TOWNSHIP - An investigation into a head-on crash that killed a Long Valley man who worked as Donald Trump's personal pilot should be completed soon, authorities said.

Raymond Ferrante, 68, was pronounced dead at the scene of the April 18 crash on West Mill Road, which occurred after an eastbound Lexus crossed over the double yellow lines and slammed into his 1961 Chevrolet Corvette, Washington Township Police Lt. Douglas Compton said.

No charges have been filed against the other driver involved in the crash, Elaine Moran, a 69-year-old from Long Valley, as the fatal accident is still under investigation by the Morris County Prosecutor's Office, Compton said Thursday morning.

Deputy Chief Denise Arseneault of the Morris County Prosecutor's Office reportedly told NewJerseyHills.com that investigators are still "several weeks" away from closing out the case.

Ferrante, who left behind a wife and three children, will be laid to rest at Arlington National Cemetery in September. A memorial service was held for him in May.

Trump issued a statement a day after the fatal crash describing Ferrante as "a fantastic pilot and a fantastic man."

"He was with me for many years and I have met few people of such quality. He will be sorely missed - both professionally and personally," Trump said.

Moran was not injured in the crash and declined medical treatment.
