Newton County Sheriff's Office investigators are looking for a Newton County man who may be possibly fleeing the state after allegedly murdering his estranged wife, who was discovered dead Saturday.

 Porfiro Guanchez, 27, who also occasionally goes by the last name Roman, is suspected of attacking his 27-year-old wife, Carmen Guanchez, who also listed the last name Cintron, in the presence of their young children and killing her at her home on Ashley Court between Friday and Saturday night, when co-workers and neighbors found her body.

"The autopsy results indicated it is a homicide," said Georgia Bureau of Investigations spokesperson John Bankhead. "We're not releasing the cause, just the manner." He previously described the victim as having no obvious fatal wounds.

Investigators also have a warrant for Guanchez with charges of aggravated assault, concealing a death and cruelty to children in the second degree in addition to the warrant for murder.

Guanchez, a Latino man about 5 feet, 200 pounds, was driving a white 2003 Ford F-series truck, possibly a 150 or 250 model, with a Georgia tag of ASI-6615.

He had dropped off the couple's children at his brother's house on Saturday, where he had been staying, said Bankhead.

Authorities suspect he may be trying to flee the state or possibly head back to Mexico, according to Bankhead.

Friends, co-workers and Carmen's roommate first became concerned when the victim failed to show up for work at an Atlanta area Hilton Garden Inn hotel and went looking for her. They discovered her body around 10:30 p.m. Saturday.

A Levi's call was issued about 6:30 a.m. Saturday morning when authorities were unable to locate the children. The call was canceled minutes later when they were discovered to be at their uncle's house, who was reportedly unaware of the situation.

Deputies had responded to a domestic incidence call shortly before the killing at the victim's home on Friday around 10:45 a.m., according to an NCSO report.

The report cited abusive language but no physical abuse and indicated no act committed with the children present. The victim told deputies there had been somewhere between one to five previous incidents.

No arrest was made because Guanchez was not at the scene, according to the NCSO.

Anyone who sees the truck or Guanchez is asked to call the US Marshals Office at 770-508-2500 or 911.
