Richard Delgado had driven into a fence in the 3800 block of Thainwood Way around 11 p.m., and was confronted by neighbors, police spokesman Mike Sullivan said.
Delgado parked his car around the corner, came back and started arguing with them, Sullivan said.
He walked back to his house, got into another car and drove into the woman, who was on the front lawn next door to the fence he hit earlier, Sullivan said.
Witnesses said it looked intentional, Sullivan said.
Delgado drove down the street, got out of the car and started running. Police caught him and arrested him on suspicion of murder.
Sullivan said Delgado is known in the Evergreen neighborhood as someone who drives recklessly.
