UPDATED 2:45 p.m., Wednesday - 

Amy Freeman Burton, 37, and her daughter Ainsley Freeman, 13, were found shot to death in their San Francisco area home Monday. They had reportedly moved from the St. Louis area in December.

Parkway School District spokesperson Cathy Kelly confirms both mother and daughter attended Parkway schools. Kelly stated in an email to Patch that Amy Freeman Burton graduated from Parkway West High School in 1993 and Ainsley Freeman attended Claymont Elementary School in Ballwin "on and off from kindergarten through fifth grade."

According to the Pleasanton, CA Patch, Burton's husband, Christopher Burton, reportedly found the victims and called police. Investigators said Burton is not a suspect, but he is a "person of interest" as they try to determine if this is a double murder or a murder-suicide. According to police, he gave a full statement and is cooperating in the investigation. Burton is Ainsley's stepfather.

There have been no arrests, nor is there a clear motive, but police have said they do not believe a killer is on the loose.

According to the Pleasanton, CA Patch, Christopher said he and his wife contacted the police and the FBI in February because Ainsley was communicating with a 16-year-old male from Kentucky, via text messages and photos.  Police do not believe that incident has anything to do with Monday's deaths.

Freeman Burton's mother, Linda Walp, lives in Chesterfield and said her daughter received death threats after police were notified about 13-year-old Ainsley communicating with that Kentucky teenager. 

Walp tells Patch she was never contacted by police, but found out about the deaths through St. Louis media reports. Walp said she spoke with her daughter on Monday, before the bodies were apparently found. 

Walp told the St. Louis Post-Dispatch her daughter and granddaughter moved from O'Fallon, MO, to California in December because Burton's husband had been relocated there for work. According to the report, Ainsley attended Fort Zumwalt South Middle School in O'Fallon before they moved out to California.

So far two Facebook pages have been created in Ainsley's memory: RipAinsleyFreeman and AinsleyFreemanneverforgotten.
