Dwayne Flourney, left, is accused of killing his father, Brian Flourney, center, and grandmother, Sandra Flourney, right.
A New Jersey man stabbed his grandmother and father to death, hid one body on a sun porch and the other in a car and had his friends over for a party, officials said Wednesday.
Dwayne Flourney, 26, stabbed his grandmother on Saturday afternoon, and when his father came home from work later that day, he stabbed him, Essex County Prosecutor Carolyn Murray and Maplewood Police Chief Robert Cimino said.
Flourney then left his father's body on the sun porch of the home at Northview Terrace, and stashed the body of his grandmother, a 76-year-old retired teacher, in the trunk of a car parked at the house.
He had his friends over for a party, and slept at the home that night, officials said.
The following day, Sunday, Flourney took his father's car and left, officials said.
Employees at the workplace of his father -- a 52-year-old investigator with the Union County Public Defender's office -- called police Tuesday after he had not shown up for work. Other concerned family members had also reached out to police by that time, officials said.
Flourney was arrested Tuesday night at the home of a female friend. He has been charged with two counts of murder, along with weapons counts, and is scheduled to be arraigned next Tuesday. Bail has been set at $1 million.
The prosecutor's office said Flourney did not yet have a lawyer.
