HOUSTON (CBS Houston) - A man thought fast and protected his family from a home invasion after three armed suspects broke into the house.

The trouble began around 8 p.m. on Thursday while the family was baking a cake. They were interrupted from the task by a knock on the door, KHOU News is reporting.

“I see a young boy and I think it is a friend of my son so I open it a little bit,” the father recalled while talking to the station. “These guys push and out comes two more, they push me on the ground.”

The suspects reportedly went after the mother of the family while the father was knocked down, as the son ran to get his father’s gun. Once he retrieved it, he  fatally shot one of the invaders.

The other two suspects then fled the scene.

After they ran away, authorities from the Harris County Sheriff’s Office were called to the scene. Soon after, the other two suspects were found and taken into the custody, the station learned.

“At this point, we don’t know what the motive is behind this home invasion, but they did force entry into the residence,” Sgt. Greg Pinkins told KHOU News.

No charges are expected to be filed against the son.
