Relatives found the body of 17-year-old Ritu Sachdeva in her Murphy home shortly after midnight on Sunday, and called emergency services.
Just a few hours later, the body of Hillary Kate Kuizon, also 17, was found in a wooded area south of Kimbrough Stadium near Murphy Middle School, police told the Dallas Morning News.
Both girls were students at Plano East Senior High School.
Family members mourned the deaths, with Sachdeva’s sister Suchi posting on Facebook that “Nothing is going to be the same.”
“I’ll always be thinking of her when doing anything good. She was so bright, beautiful, quirky, and just all around amazing, inside and out. Gone too soon, only 17 years young,” she added.

Friends of the girls added to Fox4 that neither of them showed any outward signs of being depressed. They were described as bubbly and energetic, and were liked by many.
“Just goes to show that sometimes the nicest people are hurting the most on the inside,” said one Plano East student on Twitter about the deaths.
Investigators are trying to figure out whether the deaths—suspected suicides—are related in any way.
“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.”
Police confirmed that the young women were friends.
“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,” said Murphy Police Chief Arthur Cotton in a statement.
Students told CBS that they hope the tragic deaths will spur more conversation about suicidal thoughts.
“I don’t know what the school can do, or anyone else can do to prevent stuff like this really,” said student Praharsha Sunkara. “But I really think that just talking about it would help.”
Anyone contemplating suicide or dealing with the suicide of someone they know is urged to call the National Suicide Prevention Lifeline at 800-273-8255.
