A woman from Stroud has been arrested on suspicion of robbery and murder and remains in police custody, officers said.
A mobility scooter, thought to be the victim's, was found abandoned on Bisley Old Road by a member of the public shortly before 8am on Sunday.
"It is believed that the victim was the subject of a robbery and his mobility scooter was taken," Gloucestershire Police said.
Officers are keen to hear from anyone who saw a mobility scooter with a basket on the front being used by someone in the Paganhill area of Stroud between about 2am and 4am on Sunday.

They are also keen to hear from any motorists who were driving in the area and may have dashcam footage.
