 Two Plano East High School friends were found dead within hours of each other over the weekend, and their deaths are being investigated as suicides, Murphy 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, police said. 
 
 A missing child report had been posted on social media for Kuizon on Saturday night by Murphy and Richardson police. 
 
 It’s not clear if the deaths of the two 17-year-old girls are related or if there is any reason to believe so, police said. Investigators are speaking with relatives to determine any relationship between the deaths. 
 
 “If that happened that there was some sort of pact, we need to know that because it may lead to further tragedies such as this one,” city spokesman Celso Martinez said. “We don’t know if it was but we don’t want to discount the possibility offhand.” 
 
 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. 
 
 “Our thoughts and prayers are with the two families,” said Murphy Police Chief Arthur Cotten. “We are treating these two cases with the care and compassion they deserve, and will continue to seek answers for the families.” 
 
 Classmates have taken to Twitter to express heartbreak and remember the teens. They were described as amazing friends and beautiful souls. 
 
 Plano ISD provided grief counselors at the school Sunday and will provide additional counselors on Monday, district spokeswoman Lesley Range-Stanton said.

 Relatives called 911 after finding the body of Ritu Sachdeva on Saturday in her home. Several hours later the remains of Hillary Kate Kuizon were found by Murphy officers in a wooded area just south of Kimbrough Stadium. 
 
 Investigators believe both 17-year-old girls committed suicide. 
 
 "Both deaths occurred within hours of each other under circumstances that have led investigators to presume they were both self-inflicted. No motives have been identified, and no evidence of foul play has so far been detected,” the Murphy Police Department said in a statement. 
 
 Rumors have begun circulating about a possible suicide pact. Investigators are talking to relatives to determine if there is any connection between the two deaths.

 Friends of the girls told FOX 4 neither one showed any outward signs of being depressed. They were described as bubbly and energetic. They were liked by many.

 COLLIN COUNTY (CBSDFW.COM) – It will be a somber and tough day for students at Plano East Senior High School. Administrators, staff, teachers and students are all mourning the loss of two young women. Police think the girls both committed suicide over the weekend. 
 
 As the Murphy Police Department continues to investigate the two deaths, grief counselors prepare to help students as they return to class. 
 
 Those grief counselors will be at the school for the second day in a row. A district spokesperson says about 100 people, including students and families, were at the campus Sunday to get help from the counselors. 
 
 According to police, family members found the body of 17-year-old Ritu Sachdeva at her home. Hours later, police found her classmate, Hillary Kate Kuizon. The body of that 17-year-old was found in a wooded area close to Kimbrough Stadium. According to investigators there was no evidence of foul play detected at either location. 
 
 Police say the young women were friends, and those that knew them describe both girls as smart, beautiful and nice. Student Christian Lewis didn’t know the girl’e personally but said, “I’ve seen them probably a couple times in the past. They were good students, always on time, always kept their grades up.” 
 
 Some students of campus said if there is anything good that can come out of the tragedies, it’s that maybe there will be more of an open dialogue when it comes to talking about suicide or suicidal thoughts. Student Praharsha Sunkara said, “I don’t know what the school can do, or anyone else can do to prevent stuff like this really. But I really think that just talking about it would help.” 
 
 Murphy Police Chief Arthur Cotton issued a statement saying — 
 
 “Our thoughts and prayers are with the two families. We are treating these two cases with the care and compassion they deserve, and will continue to seek answers for the families.” 
 
 Police say they’re still trying to determine if the deaths are related, but at this point it’s not clear if there is a connection. The medical examiner will determine the exact cause of both deaths. 
 
 Anyone contemplating suicide or is dealing with the suicide death of someone they know is encouraged to call the National Suicide Prevention Lifeline to talk with a skilled, trained counselor at a crisis center in their area. Call 800-273-TALK — that’s 800-273-8255.

– On Saturday night, 17-year-old Hillary Kate Kuizon was reported missing. By a few hours after midnight Sunday, both she and a friend, 17-year-old Ritu Sachdeva, had both been found dead by suspected suicide in Murphy, Texas. "If ... there was some sort of pact, we need to know that because it may lead to further tragedies such as this one," a city spokesman says, per the Dallas Morning News. "We don’t know if it was but we don’t want to discount the possibility offhand." Relatives found Ritu's body in her home, and within just a few hours, police found Hillary's body in a wooded area. The medical examiner has yet to release the causes of death of the Plano East High School students—who were friends, police tell CBS DFW. "Both deaths occurred within hours of each other under circumstances that have led investigators to presume they were both self-inflicted," says the Murphy Police Department in a statement. "No motives have been identified, and no evidence of foul play has so far been detected." Friends of the girls tell Fox 4 they didn't seem depressed, and were well-liked.
