If there is something in the makeup of Jason Smith that might have presaged the slaying to which police say he has confessed, nothing was immediately apparent Thursday.
Neighbors in the Crescent Lane section of Levittown, Bucks County – where the 36-year-old exterminator lived with his girlfriend, their young daughter, his girlfriend’s mother, and other relatives – described him as helpful, a family man who took his boxer, Tyson, out for frequent walks.
They said he showed no signs of a violent temper.
Yet Philadelphia police officials, at a news conference Thursday, said an explosive argument between Smith and Melissa Ketunuti apparently triggered a murderous rage.
