Fire officials said the two deaths are being treated as possible homicides. Jones, who reportedly rented the basement of the University Place home, was discovered dead downstairs while the woman was found unconscious upstairs in the kitchen.
According to police, the woman's 23-year-old nephew, who used to also reside at the home, was in police custody for questioning. Authorities are currently trying to determine where he was during the time of the fire.
Arson investigators were apparently called to the home last week because of "trouble." During that incident, deputies apparently had to use a beanbag gun and a taser to arrest the nephew after his Pitt bull threatened the neighborhood.
Court records indicate that felony harassment charges were filed against the nephew, who also apparently has history of mental illness, in April 2008 after he allegedly threatened to kill his own mother. That case was set to go to trial in August.
J.J. Jones was the backup quarterback for Joe Namath when he played for the New York Jets in 1975-1976. Jones also played for Tennessee State in his college years.
