A young mother in Tulsa, Oklahoma was accidentally killed by her three-year-old son, who reportedly shot her dead with a semi-automatic gun he found 'under the couch'. Reports suggest that 26-year-old Christa Engles was changing her one-year-old daughter's nappy when the incident took place.
Her body was found by her mother-in-law who also lives in the same house.
Meanwhile, her husband Brian, who is a truck driver, was out of the state at the time of the incident. In a social media post, he said: 'I lost my wife to an accident yesterday.
'Don't forget to tell your loved ones they are loved. You really never know when the last "I love you" really is the last.'
Dave Walker, a sergeant in Tulsa Police's homicide division, said: 'There's several guns in the house, it's going to be a large-caliber handgun.'
A Tulsa police spokesman said: 'The investigation revealed that the three year old accidentally shot his mother. The victim was transported to St. John and was pronounced dead at 5:38pm.
'The husband/father was notified of the tragedy and returned home. The three-year-old was interviewed by child specialists and confirmed what the evidence led investigators to assume.
'The neighbors, family, coworkers, and church family quickly gathered around this family in support of them during this terrible time.'
