DAVIDSON COUNTY, N.C. — The Davidson County Sheriff’s Office announced Thursday that it has enlisted the help of the United States Marshal Service Fugitive Task Force and North Carolina Highway Patrol to help find two suspects wanted for a double homicide.

Lloyd Franklin and Jennifer Lanning are wanted  in connection to the deaths of 82-year-old Davie Lee McSwain and 78-year-old Joan McSwain.

Sheriff David Grice said, “I think what makes this especially heinous is these individuals were in their home just doing what they are supposed to be doing… and then this individual enters in there for whatever reason, to get a little cash or whatever reason they came in for, and it culminates in both these folks being killed. I’m sorry, but that’s just trash.”

Detectives determined that the apparent motive was robbery because some areas of the house had been ransacked.

Deputies were called to the home at 362 Garcia Kennedy Road by family members, who made a daily visit to the home and found the couple dead.

Authorities have focused on the couple’s missing dark blue 2006 Chrysler Town and Country van with the license plate XRX-2142.

SBI Special Agent in Charge Scott Williams advised, “Have an open eye on the highways. We don’t have any idea the direction of travel these folks are going so they could pop up anywhere.”

Since the homicide, the pair’s crime spree has continued.

On Tuesday, they were caught on a surveillance camera robbing a Rite-Aid Pharmacy in Roanoke Rapids, N.C.

Grice and Williams believe as of Tuesday, the suspects were still in the minivan they stole from the McSwains.

They said it’s possible they’ve stolen new tags to replace the current ones, but their investigation indicates the same tag is on the van.

Before that robbery, they allegedly robbed two other pharmacies — one in Aberdeen, N.C., and the other in Georgetown, S.C.

For the first time, investigators also said it’s possible a third suspect was involved during and/or after the homicides, and they are interviewing people about that possibility.

They believe Lanning met up with Franklin after he committed the homicides and it seems the couple has been together ever since

Even though Franklin is the one in the surveillance pictures, they are almost certain he is still with Lanning because witnesses described her in the van in the parking lot during the drugstore robberies.

Franklin, 34, is wanted on two counts of first-degree murder and Lanning, 38, is wanted on one count of accessory to murder after the fact.

Franklin and Lanning are still armed, dangerous and desperate, Williams warned. They ask anyone who sees them not to approach them, but to call 911.
