DISTURBING CONTENT WARNING: Illegal accused of killing Georgia grandmother faces new disturbing charges

In addition to felony and malice murder, Sagastume-Rivas is now being charged with aggravated assault, aggravated sexual battery, rape and necrophilia.

Authorities say Sagastume-Rivas choked Williams until she was unconscious and then put his knees on her neck and used his full body weight to kill her. Williams was later found in the bushes of a neighborhood yard in Marietta, a popular Atlanta suburb.

The new charges were released in an indictment published last Friday.  

According to the woman's family, she had been worried about being followed in the days leading up to her murder.

Her family is now left shocked and devastated by the killing.

There is no indication of a plea by the defendant on the indictment.

"He was issued a notice to appear and paroled into the country by the previous administration," the statement said. "A judge ordered him removed on July 11, 2023. On March 18, 2025, he was arrested by the Cobb County Police Department for capital murder and other crimes."

"This illegal alien should have never been in our country in the first place," said Noem. "President Trump and I are putting the safety of Americans FIRST."
