Harris County Constable Pct. 4 investigators told KTRH TV partner KPRC Local 2 that William Blackburn kicked the front door in and that he had a knife when he came face to face with the couple inside their home in the 14200 block of Barrone.
Deputies say Blackburn, 33, was the one who got scared when he was spotted and ran out of the house. Luckily, several neighbors were outside when it happened and rushed to help the elderly couple.
"The (homeowner) came out and said, 'Somebody help,'" neighbor Alfred Lopez said. "We started chasing the guy and eventually the whole neighborhood started following them and chasing them all the way down the street."
