Authorities say an 89-year-old man has been charged with murder after a woman was run over with a car several times in San Antonio.

Police arrested John Bogard at his home Saturday after witnesses said he ran over the woman, described as being in her 80s, following an argument in an elementary school parking lot.

Authorities say Bogard allows homeless people to stay at a property near the school and that he got into an argument with the woman as she was leaving the property.

Police say witnesses told them that Bogard got into his car and ran the woman down, then backed up and ran her over again. Police say according to the witness accounts, Bogard got out of his car to look at the woman before driving away.

Two witnesses with permits to carry a weapon shot at Bogard's car and blew out a tire.

It's not clear if Bogard has an attorney to comment on his behalf.
