A body has been found after a youthful Adelaide mum vanished while getting her little girl over about fourteen days prior. 

Charlene Warrior, 21, was most recently seen when she went to get her one-year-old little girl from her ex-accomplice's home in Bute, on the Yorke Peninsula, on September 18. 

On Sunday evening, police were called to Martin Street in Bute after an individual was discovered dead. 

"The expired individual still can't seem to be officially recognized anyway it is accepted to be that of missing lady Charlene Warrior," SA Police said. 

"Her demise has all the earmarks of being non-dubious anyway police are as yet exploring and will set up a report for the State Coroner." 

Fighter's family given a request for data recently after not having any contact with the 21-year-old for a very long time. 

"There's no kind of way she would leave her little girl," Warrior's sister Theresa Newchurch told 7NEWS, adding she was sure Warrior wouldn't forsake them. 

"She adores her little girl more than life itself. 

"Her little girl is her reality." 

Champion's mum Alma added she had been anxious after not seeing her girl or granddaughter. 

"She cherishes her family and she generally gets back home to her mum," Alma told 7NEWS. 

"It's sad." 

Police held onto things of attire on a side of the road in Bute on Sunday. 

Prior, a neighbor in Bute said she heard shouting coming from the property this week. 

"At 12 PM, I heard her shouting, disjointedly. Shouting as loud as possible, wailing," neighbor Cheryl Sawley said. 

"Somebody was with her attempting to quiet her down however she was shouting." 

Police attempted a broad quest for Warrior in the Bute region on Friday and proceeded with the pursuit over the course of the end of the week. 

Hero's girl Amethyst is protected, police say. 

Investigators are exploring the reason for her demise.
