Sam Keen, a 27-year-old Houston firefighter and Marine veteran, was shot dead on March 17, 2014, after mistakenly entering his next-door neighbor’s home in Porter, Texas. Keen had taken a cab home while celebrating St. A 64-year-old woman who was home alone fired two shots through the door, believing she was facing an intruder. Keen was taken to a Houston hospital and later pronounced dead.

The woman was not immediately arrested; the case was sent to a grand jury to decide whether charges should be filed. Houston Mayor Annise Parker described the death as a confluence of events, and colleagues remembered Keen, who joined the Houston Fire Department in 2010, with streets of support including fire stations flying flags at half-staff. The grand jury declined to press charges, finding the shooting to be an act of self-defense.

Did anyone in Porter at the time notice increased confusion that night or have information about how Keen ended up at the wrong house?
