An active US soldier who was charged with murder when police found his wife's body in the trunk of his girlfriend's car has been pictured.

Corporal Logan T. Kyle, 22, was arrested near Fort Polk, Louisiana, early on Monday after police received a tip that the remains of his wife, Shelena Kyle, 22, were inside the vehicle.

His mistress Sarah Parker, 24, was driving at the time, with her two toddler children sitting in the back.

She was also taken into custody because she was allegedly trying to help Kyle get rid of the corpse, The Calcasieu Parish Sheriff's Office said.

Logan serves with the 3rd Brigade Combat Team, 10th Mountain Division, according to Army Times.

Shelena was from Lafayette, Indiana, and had married Logan on August 9, 2016, according to her Facebook page.

Sheriff Tony Mancuso said during a press conference on Monday that Parker was helping Logan Kyle get rid of the corpse.

Cops believe Logan Kyle and Parker met after he killed his partner, Shelena, on the base at Fort Polk.

The two were driving around looking for a place to dispose of the body when they were stopped.

'In many cases, we don't get a call until the body is actually found,' Mancuso told KATC-TV. 'We actually got this one before it was dumped which made it easier.'

Parker was arrested and booked into the Calcasieu Correctional Center and charged with obstruction of justice for aiding the suspected killer.

Parker also faces a charge for failure to report a homicide. KLFY.com reports her bond is still pending.

Parker's children, ages one and two years old, were taken into custody by the Department of Children & Family Services.

She may face more charges relating to cruelty to juveniles for putting her toddlers in a dangerous position.

'What disturbs us about that as law enforcement officers is, you know, when we come in contact it would not be abnormal for us to draw our weapons on what we consider a felony stop,' Mancuso said.

'If we had to shoot into this car or they shot back at us or for some reason we could have injured two innocent children.'

Logan Kyle was arrested by CPSO on Monday at around 12.15am for the alleged homicide.

Members of the US Army Criminal Investigation Division were notified of the finding of the body of Shelena Kyle (left) and Kyle Logan (right) was turned over to investigators at Fort Polk

Members of the US Army Criminal Investigation Division were notified of the incident and the service member was turned over to Army investigators at Fort Polk.

'We are deeply saddened by the loss of this Patriot Family member,' Col. Kendall J. Clarke, brigade commander, said in a statement released on Monday. 'She was a member of our family and her death affects us all. We send our most sincere condolences to her family and friends.'

The incident is under investigation by the US Army CID with CPSO Detective Keeba Barber also leading an investigation.

'I think this is just the start in what we believe are strange events that took place both in Leesville and our parish,' Calcasieu Parish Sheriff Mancuso said.

Fort Polk Army Base is located in Vernon Parish, which is approximately ten miles east of Leesville, Louisiana.

Kyle enlisted in the Army four years ago. He was stationed at Fort Polk in February 2017, as an infantry fire team leader, according to the command's release.
