A second arrest has been made in connection to a murder investigation in Bismarck.
A 20-year-old Stanley, North Dakota man was arrested for murder last night in connection to the death of John Swain.
Earlier this week 25-year-old Theo Crowe of Trenton was arrested and charged with murder in the death of Swain.
Lt. Gary Malo says through interviews Bismarck police identified a second person of interest.
We have already interviewed him in the past so he gave us some information and through our investigation we obtained more information where we wanted to re interview him and at the conclusion of the interview we had enough information to place him under arrest for also the homicide of John Swain," says Lt.Gary Malo.
Yesterday a body was recovered in Poplar, Montana at the home of Crowe's grandmother.
Police believe it's Swain's but an autopsy has not been done yet to confirm it.
These are pictures from Louis Montclair of the Fort Peck Journal.
He says he saw detectives digging up the body in the backyard Wednesday.
18 year old Swain was reported missing in Bismarck May 11th.
The case turned into a murder investigation after a Bismarck resident found Swain's clothing, a cell phone and a bloody knife in an outdoor trash can.
Swain had recently moved to Bismarck to look for work.
Crowe is in custody in Williams County on un-related charges.
An army official says Crowe was discharged from the U.S. Army in February.
Malo says he doesn't expect any further arrests in connection with the homicide.
He says an autopsy on the body recovered yesterday in Poplar, Montana hasn't been done yet and Swain's body has not been returned to Bismarck.
