Eyewitness News uncovered a search warrant focusing on the potential father of Hawa Gabbidon's baby.
Gabbidon's body was found at Elder Park in north Charlotte last summer.
The warrant shows Jamar Augustus and his mother wanted Gabbidon to have an abortion.
Investigators said he lied to them about being in contact with Gabbidon and about being on Facebook.
However, they do not say he is a suspect in her murder.
In December, police were investigating the other potential father, Darne Brown. They said he lied about where he was that night, was in the area at the time and one of his friends found Gabbidon's body.
People walking through Elder Park on Rockwell Church Road found Gabiddon's just after midnight on July 10.
