The daughter of a woman who went missing in South Carolina in 2017 revealed the reason why she thinks accused killer Rex Heuermann is linked to the case.

The Sumter County Sheriff's Office has already confirmed that the daughter of Julia Ann Bean is cooperating with police, and News 12 has learned why she believes Heuermann may have been involved with her mother, and possible disappearance.

"He looked similar to the man she had seen in the media, known a Rex Heuermann," says Dr. Mark Bordeaux, with the Sumter County Sheriff's Office.

The possibility that Bean may have had a relationship with Heuermann was brought to the department's attention on Aug. 20, just one month after his arrest.

"When that person, an acquaintance of Mrs. Bean, came to our attention with this story, well we seize on that until we have an answer," says Bordeaux.

The last time Bean's daughter, Cameron, saw her mother was when they were going to get their nails done. She says they were driven by a man she didn't know. The daughter gave them both tickets to her graduation, which was the following day.

"Her graduation day came around and she did not see her mother or the unknown male," says Bordeaux.

The last communication Bean's daughter had with her was a text message asking for graduation photos. According to the Sumter County Sheriff's Office, when the daughter tried to visit her mother, she could not find her and notified authorities.

Heuermann owns property in Chester, South Carolina, which is about an hour and a half away from where Bean disappeared.

"You can never say 100% this is likely, or this is not likely," says Cr. Louis B. Schlesinger, a professor at John Jay College of Criminal Justice. The authorities are doing the right thing by investigating it. I wouldn't put a great deal of hope in that you are going to solve and unsolved crime.

At this time there is no direct link between Bean and Heuermann, but the Sheriff's Office tells News 12 that they are following every lead.

The Suffolk Sheriff's Office also confirmed that Heuermann stands 6 foot 4 inches tall and weighs about 280 pounds, which is why he may have stood out to someone who says they recognized him.
