HARRISBURG, Penn. (WGGB) – Police in Pennsylvania are asking the public in their state and in Massachusetts for any new information in a 44-year-old homicide of a now identified Mass. Marine.
Penn. State Police say that on November 18, 1968, one of their state troopers was on routine patrol along the Pennsylvania Turnpike when he saw a body sitting up along the roadway in Chester County, about 30 miles northwest of Philadelphia.
When the trooper went to check on the man, they found that the person, a male who had no identification on him, was dead. An autopsy found that he died from a stab wound through the heart.
For over 40 years, that body remained unidentified and he was classified as a ‘John Doe’ until a recent DNA analysis of bone fragments uncovered that the body was that of then 20-year-old Marine Corporal Robert Daniel Corriveau, originally from Lawrence, Mass.
Cpl. Corriveau, who enlisted in the Corps in 1965, was on active duty and had been wounded in action three times while serving in Vietnam in 1967. He had been awarded two Purple Hearts for his line-of-duty injuries.
Investigators say that Cpl. Corriveau was receiving psychiatric treatment at the Philadelphia Naval Hospital for a combat related condition when he disappeared in the morning hours of November 18, 1968 – the same day he was found dead.
Now, Pennsylvania State Police are looking for help from the public in two states to try and piece together and solve the case to what happened to Cpl. Corriveau.
They are especially hoping to hear from members of the Marine Corps or Navy who may have served with Cpl. Corriveau, or Naval personnel or patients who may have ben at the hospital in October and November 1968.
Anyone that may have information is asked to call the Pennsylvania State Police at (610) 268-5158 or send them an email.
