William Edgar McCallister, 43, of Seffner, Florida, was killed on March 22, 2017, at a home on the 1000 block of Lianne Place. Deputies from the Hillsborough County Sheriff’s Office responded to a 911 call from the suspected shooter at about 10 p.m. and found William McCallister deceased inside the residence. Another man, identified as David Jack McCallister, 51, suffered non-life-threatening gunshot wounds.

Investigators say the men knew one another and that the shooting was not random. Detectives reported an incident shortly before 10 p.m. led one man to pull a gun and shoot the two others, but the exact nature of that precipitating event was not disclosed. The alleged shooter remained at the scene and was hospitalized for unrelated medical issues; no arrests or charges were reported at that time.

Does anyone have information about the events on Lianne Place that night or about the relationships between the men involved?
