Police seek tips in 1968 Pa. Turnpike stabbing of recently identified Marine
The remains of Marine Corps Cpl. Robert Daniel Corriveau remained unidentified for nearly 44 years, and authorities still don't know who killed him or why.
Corriveau was about to celebrate his 21st birthday on Nov. 18, 1968. His body was found sitting upright along the Pennsylvania Turnpike about a mile east of the Downingtown interchange in Chester County, about 30 miles northwest of Philadelphia. He had been stabbed in his heart.
Because he carried no identification, he was considered a John Doe until July 2009, when his remains were exhumed and bone samples submitted to the University of North Texas Center for Human Identification. His DNA profile went into a national missing persons database.
State police also requested assistance from the Naval Criminal Investigative Service Cold Case Unit and the Marine Corps Absentee Collection Unit. Authorities suspected he might have been in the military because of his tattoos.
His identity was confirmed by DNA analysis on May 31.
State police are asking anyone who served with Corriveau or was hospitalized with him in Philadelphia or during a previous stay at Chelsea Naval Hospital in Massachusetts to contact investigators by email at RA-1968MarineDeath@pa.gov or by calling 610-268-5158.
Corriveau, a native of Lawrence, Mass., had been an active duty Marine and was wounded in action on three occasions in Vietnam in 1967.
When he disappeared, he was a patient at Philadelphia Naval Hospital receiving psychiatric treatment for a combat-related condition. Hospital personnel reported him missing. That same morning, his body was found.
Anyone with information about his death might be eligible for a cash reward by contacting Pennsylvania Crime Stoppers at www.PACrimeStoppers.org or calling 1-800-4PA-TIPS.
