WEST BLOOMFIELD, Mich. (WXYZ) - The 7 Action News Investigators are learning new details that led up to the fatal shooting of 17-year-old Jonathon Hoffman.
The teen's grandmother, 74-year-old Sandra Layne, is charged with his murder. Sources have told 7 Action News that Layne feared her grandson was using the synthetic drug K2 and feared Hoffman would kill her in a violent rage.
A new question has also been raised in the case as a police source is telling 7 Action News that Layne sent her husband to walk the dog shortly before the fatal shooting.
A number of incidents appear to have led up to the fatal shooting at the Maple Place Villas condo complex in West Bloomfield.
The first came in March when Layne called police saying Hoffman was out of control. Sources say when police arrived on the scene they found him on the front lawn making nasty comments about his mother and yelling at his grandmother.
Officers were able to calm the situation down. Hoffman's mother was not present at the time.
Then, in April, Hoffman was placed on probation for using marijuana. At that time it was determined that by the court that Hoffman was a threat to one or more people. The court order does not specify who those people were.
As a condition of his probation, Hoffman was ordered to undergo outpatient treatment, avoid drugs and alcohol and undergo random drug and alcohol testing.
Later on in April, Layne purchased a Glock pistol at the Target Gun Shop in Orchard Lake. At the time she also underwent training on how to use the gun.
Finally, on the day of the shooting, Hoffman was found to have violated his probation after testing positive for K2. This apparently led to an argument between Hoffman and his grandmother.
