Clifford Frederick Gant, 31 was taken into custody Sept. 1 in California by U.S. Border Patrol on a felony arrest warrant for first-degree murder in the slaying of a woman on Tucson's north side, police said.

Kathleen Lorraine Huffer, 52, was found August 30, dead in her house in the 3000 block of North Richey Boulevard. She suffered blunt force trauma, authorities said. 

Gant was detained by agents Sept. 1, when he attempted to re-enter the U.S. at the San Ysidro Port of Entry, said Sgt. Pete Dugan, a Tucson Police Department spokesman.

San Ysidro is the largest land border crossing between San Diego and Tijuana, Mexico.

Gant was booked into the San Diego County jail on the felony warrant. Tucson police homicide detectives went to the jail and spoke with Gant who is awaiting extradition to Tucson, said Dugan Friday.

On Tuesday shortly before 7:30 p.m., Huffer was found after persons flagged down officers and asked them to check Huffer's welfare inside the house. The neighborhood is south of East Fort Lowell Road and west of North Dodge Boulevard.  

Homicide detectives discovered that Huffer's vehicle was missing from the house, and family members said no one should be in possession of the vehicle. The vehicle was then reported stolen, said Dugan.

Detectives also found out that Gant had been staying with Huffer for several months. Investigators were not able to find Gant, but learned that Huffer's vehicle had entered Mexico through the San Ysidro crossing on Monday, Dugan said. He said images showed Gant driving the vehicle.

Based on that information and evidence collected at the scene, detectives obtained the arrest warrant, said Dugan.
