DAYTON, Ohio -- A Dayton couple headed out for an evening walk and ended up being robbed and stabbed just yards from their home. The incident happened Tuesday near the intersection of Wayne and Wyoming in Dayton.

Authorities said they are not the only victims reporting similar crimes in the area. Police said in the last week, there have been at least three reports of people being robbed at knifepoint in East Dayton.

Investigators are not saying if the cases are related, but the most recent victims want other people to be aware.

Joanne Johnson and her husband, Floyd, were walking to the Sunoco station on Wyoming Street Tuesday night when a man charged at them, demanding money. Joanne said she gave the man all the cash she had, which was $1.30. However, officers said the man kept coming at them with a large butcher knife.

Joanne said she and her husband were both struck in the hand. She said her husband was cut nearly to the bone.

Authorities said the Johnson's are not the only victims of this kind of attack. Police said three days earlier, an 89-year-old man who was around the corner on Wayne Avenue was threatened to have his throat slit if he didn't hand over his wallet.

Investigators said the elderly man had pulled over to wipe off his windshield when he was approached by a man with a knife.

Police said earlier that day, another person fell victim to a similar crime on East Fourth Street. Investigators said none of the victims was seriously hurt, but the Johnsons said they will be more cautious in the future.

Authorities said no one has been arrested in the attacks. They said the descriptions of the attacker have been too vague. Police said two victims reported a white male around 40 years old. The couple said the man may be Hispanic or a light-skinned African American with braids.
