Two Plano East High School friends were found dead within hours of each other this weekend and their deaths are being investigated as suicides, says Murphy, Texas police said.

Relatives found the body of Ritu Sachdeva in her Murphy home shortly after midnight Sunday and called emergency services.

A couple of hours later, police found the body of Hillary Kate Kuizon in a wooded area south of Kimbrough Stadium, near Murphy Middle School and McMillen High School, also near Murphy.

A missing child report had been filed for Kuizon on Saturday night by Murphy and Richardson Police Departments.

It’s not clear if the deaths of the two girls are related, but investigators are speaking with relatives to determine any relationship between the deaths.

The causes of death will be determined by the medical examiner.

No evidence of foul play has been found. Murphy police believe there is no threat to area residents.
