(WBIR) Officials confirmed Friday that Jacob Allen Bennett, 26, is the suspect in custody for the quadruple homicide in Cumberland County.
Investigators found Bennett in Rhea County Thursday night and arrested him on an unrelated charge. The 26-year-old suspect is in custody at the Cumberland County Sheriff's Office. A source close to the investigation said they want to move quickly on this case and are considering the possibility of a special called grand jury for charges.
Friday, authorities released the identities of the four victims found shot to death in a car on Renegade Mountain in Cumberland County Thursday morning.
According to a Tennessee Bureau of Investigation release, the driver of the vehicle was Rikki Danielle Jacobsen, 22. The three teen passengers were Steven Presley, 17, Dominic Davis, 17, and John Lajeunesse, 16. Officials have submitted their bodies for autopsy.
The four victims were discovered in a Blue Dodge Neon early Thursday morning by a member of the Renegade Mountain community. The development is about 3000 acres with 141 homes, but only 43 of them are occupied by full-time residents.
Cumberland Co. Chief Investigator Cox said in a press conference Friday afternoon that this is a very traumatic case because of the number and age of the victims. He added he has never witnessed a case like this in his 14 years with the sheriff's office.
"This (homicide case) is very devastating to the victim's families and (Cumberland County) students," said Cox in a press conference Friday afternoon.
A TBI spokesperson said in Friday's press conference that they knew Bennett was a suspect very early on in the investigation. According to officials, Bennett has a lengthy criminal history, and Cumberland County Sheriff's Office confirmed Bennett has been in their jail "maybe five times."
TBI wouldn't confirm whether drugs were involved in the murders.
"In a lot of cases like this, drugs are involved. That's why we are against any drug legalization," said a TBI spokesperson in the conference.
Cox said investigators have been working around the clock since the bodies were discovered at about 7:00 a.m. Thursday.
"There is still some work to be done on this case. Agents are working right now," said Cox.
Authorities are not releasing exactly what occurred on Renegade Mountain because they believe it isn't appropriate at this point. TBI, Cumberland County Sheriff's Office and the district attorney said their investigation is continuing, and they're still collecting evidence.
In a press conference Friday afternoon, Cumberland County Superintendent Donald Andrews said grief counselors are available at all three high schools. He said the district is working with students to try to regain a sense of normalcy.
