New court documents: Murder suspect stabbed ex-girlfriend in San Marcos three times, left his baby


SAN MARCOS, Texas (KXAN) — New court filings indicate the man accused of murdering a San Marcos woman is her ex-boyfriend, and the baby left near her body was his own.

The San Marcos Police Department said a murder warrant was obtained for Kiril St. John Sokoloff, 42. He was transported back to the Hays County Jail Monday afternoon from San Antonio.

Police found 36-year-old Cheryl Ritzer dead on her backyard patio on Friday, March 12, according to court documents filed Monday.

SMPD said on Friday just after 8:30 p.m., officers did a welfare check at a home near the corner of North Bishop Street and Craddock Avenue. According to court documents, Ritzer’s father told officers he spoke with his daughter on the phone everyday but couldn’t get a hold of her that day.

When they arrived, officers knocked on the door and didn’t get an answer.

They went to the back of the home where they found the body of Ritzer on the patio, SMPD said. A search warrant affidavit said a long, butcher-type knife was found in her back.

Officers said her baby was next to her body and was later found not to have serious injuries.

The medical examiner’s office later found Ritzer had been stabbed three times, had fractures on the side of her head and a broken nose, according to the documents.

The documents stated detectives believe Ritzer was killed sometime on Thursday, March 11. A neighbor told police they heard the baby crying for about an hour that night but did not hear any fighting, according to filings.

According to search warrant documents for the home, officers found blood on the wall near the back door and on the kitchen floor. They also found a trash bag filled with bloody rags in the master bedroom.

Warrants explained Ritzer’s father told police she had recently broken up with Sokoloff, who was her boyfriend.

Her father also explained Sokoloff had moved out after the breakup but was suffering from mental illness. He said the baby at the scene was Sokoloff’s biological child.

An arrest affidavit said Sokoloff was found at a hotel off Wonder World Drive on Saturday. When officers interviewed him, they found he had injuries indicative of a physical fight. Sokoloff changed his story on how he got the injuries, officers reported, saying he was involved in a fight with men at Ritzer’s home who were being disrespectful.

Neighbors said they didn’t see additional cars or hear voices that would indicate Ritzer had company over that day, according to the affidavit.

Blood stains were also found on Sokoloff’s clothing, but the fight with the men he described and the injuries he got wouldn’t have produced blood, according to the responding officers.

Court documents said Ritzer’s father told police a paternity test indicated Sokoloff is the baby’s father. A San Marcos detective noted Sokoloff never asked how the baby was doing and “instead spent the interview talking about how he does not believe he is the father to Cheryl’s child.”
