Jeffrey Flores, 25, of Pinole, was arrested at the scene in
connection to the two homicides, according to police.
The man and woman found
dead, who are in their 50s or older, were relatives of Flores. Their names
have not yet been released by investigators.
KTVU television reported the victims were Flores' grandmother, 76-year-old Nona Flores, and his uncle, 54-year-old Tony Flores.
A woman who is believed to be Flores' sister was also at the home
when officers arrived on the scene, along with three children under 10 years
Officers responded to the 1100 block of Tara Hills Drive for an
unknown problem around 2:30 a.m. Friday, police said.
Officers arrived at the two-story home and spoke to a resident who
said there might be injured people inside.
Police served a search warrant at the home later in the morning
and were collecting evidence a short time after noon.
While an investigation is ongoing, police said this appears to be
an isolated incident and all persons of interest are in custody.
Flores was booked into the Martinez Detention Facility on
suspicion of two homicides. He is being held in lieu of $2 million bail.
The killings are Pinole's first homicides this year and are
believed to be the first murders in the city since 2011.
Anyone with information about the case is asked to call Pinole
police at (510) 724-8950.
