Now, Nathaniel Jackson is getting more than 11 years in prison for two counts of first-degree aggravated robbery and one count of first-degree burglary and assault of a person.

The 60-year-old St. Paul man has 10 aliases and several prior felony convictions.

He attacked and robbed the couple at their home in Battle Creek-Highwood in March 2015, according to the criminal complaint.

He knocked the 67-year-old male victim out of his wheelchair and hit the 64-year-old female victim on top of the head, leaving a bloody injury. He took the woman’s purse and left, legal documents say.
