Smithfield, Va. - On Friday during a press conference, Smithfield authorities announced that the case involving a woman who was once reported missing is now being investigated as a homicide.
Officials say she was attacked as soon as she came through the door. She was visiting a bedridden neighbor at the time.
Police believe the person responsible for Naira Davis' death is the son of the neighbor.
"Why this occurred, we really do not have any answer. Other than that, we are very confident in the evidence that we have and that we have the individual in custody who's responsible for this heinous crime," said police.
Davis' friend called on Thursday saying that Davis had not shown up to the home. Her husband then filed a missing persons report.
Police received a call from the caregiver of the woman who Davis was visiting and she says she discovered Davis' body.
Naira Davis' car was found near her home this morning with the windows down and keys still in the ignition.
Now authorities have a warrant for David Joseph Ricciardi. Witnesses say he left his home in Davis' car.
Right now, Ricciardi has only been charged with unlawful use of a vehicle but police expect to charge him with first-degree murder.
Police have not said what kind of weapon was used in the attack. They say he does not have a violent history.
"We know of him. There have been some minor disturbances in the past but nothing that would have given us any indication this could happen," police say.
