SPARTANBURG, S.C. -- Investigators arrested a sixth person on Thursday in connection with a double homicide that happened in January.

Rudis Ventura, 26, of Marietta, Ga., was arrested without incident around 10:30 p.m. by Cobb County sheriff’s deputies.

Ventura was charged with two counts of murder in connection with the shooting deaths of 21-year-old Teresa Martinez and 24-year-old Hugo Hernandez. The couple was found shot multiple times inside their home by family members on Jan. 25.

On Wednesday, deputies announced the arrest of five people in connection with the case.

Investigators said that Hernandez owed 32-year-old Juan Vazquez money for some marijuana.

When Vazquez never received payment for the drugs, he assembled a group of three people to collect the debt, investigators said. They said 25-year-old Edgar Aviles, 37-year-old Yesenia Ramirez and 28-year-old Eli Pineda, all of Emerson, Ga., were sent to the couple’s home to recover the drugs or the money.

Investigators said Vazquez offered the group half of anything they recovered for their effort and an SUV.

Vazquez and 37-year-old Jose Arevalos, who investigators said helped organize the hit, were already being held at the Spartanburg County Jail after being arrested on Jan. 30 on drug trafficking charges.

Aviles, Ramierez and Pineda were also being held at the Spartanburg County Jail after waiving extradition.

All five of the people arrested on Wednesday were charged with two counts of murder.

Bond was not assigned to any of the suspects.
