DALLAS (CBSDFW.COM) – A woman in Dallas is raising concerns after home security video captured a man following her home during her morning jog. Fatima Dominguez first noticed the stranger sitting in a van at a street corner by her home, and instinctively felt that something was wrong.

“When I saw him roll down the window, I thought, he’s trying to talk to me,” Dominguez said. “So, I decided to run faster.”

This happened on Wednesday morning along Duncanville Road in west Oak Cliff.

Dominguez never suspected that, as she continued running, the man was trailing closely behind. “I didn’t look back, because I had my earphones on,” she said.

Cameras show the man pull up to the house as Dominguez dashes inside. The van then moves several doors down. The driver then reappears and walks up the driveway to the front door. Dominguez believes that he may have spotted the camera.

“Usually, when people come up, they’ll ring the doorbell or they’ll knock and I can see their face,” Dominguez explained. “But not him. He stretched, put his arm out, rang it and stepped back.”

Dominguez regrets not looking before she opened the door. “When I saw his face, I was in shock,” she said. “This is that dude from over there.”

“He said, ‘Is there a Robert here?’ And I said, ‘Robert? There’s no dang Robert here,’ and I shut the door,” Dominguez added.

The woman immediately locked her door and grabbed her gun. “He probably had really bad intentions — to hurt me,” she said about the encounter. “I didn’t want him to do that to anyone else, so I really wanted him to walk back to my door.” Dominguez also wants his picture made public. She has turned the video over to police in case the man shows up anywhere else.

In the meantime, Dominguez is making changes to her routine, promising to be more prepared if she ever sees him again. “He won’t be walking away,” she said. “Not next time.”
