Flaherty even put his hand on the camera, apparently indicating that he did not want the family to know he was the one at the door.

Both D & # 39; Errico, who was in San Diego for a business trip, and his family could see Flaherty through the Ring cell phone app.

The motion detection application allows owners to see everything that happens outside their property on their phones.

When D & # 39; Erricos saw Flaherty at the door of their house just before 11 pm, they immediately called 911.

D & # 39; Errico's wife hid in the bathroom with her 17-year-old son and 12-year-old daughter as they waited for the police to arrive, fearing for their lives.

"Not being home, not being able to do anything, I felt like I was in the movie Taken," D & # 39; Errico told the Sun-Sentinel.

D & # 39; Errico told investigators that Flaherty's wife and daughter had left him alone a few days before, after he threatened to shoot and kill them.

When the D & # 39; Erricos saw Flaherty at the door of their house just before 11:00 p.m. Wednesday, they immediately called 911

The Errics had allowed Flaherty's daughter to stay at her house, which is 200 feet away, for two nights because she was afraid of him.

D & # 39; Errico's son, 17, also told police that Flaherty had threatened the family in the past and that he has a history of alcohol and drug abuse, according to CBS 12.

The teenager believes that Flaherty wanted to kill his family because they let their daughter stay with them.
