Two Texas teenagers were found dead due to apparent suicides within hours of each other, police said.
The two 17-year-old girls, Ritu Sachdeva and Hillary Kate Kuizon, were found dead within hours of each other over the weekend of Jan. 30, the Dallas Morning News reported. Both teens were students at Plano East High School in Plano, Texas.
Sachdeva's relatives found her body at her home in Murphy, Texas, shortly after midnight on Jan. 31. She had reportedly overdosed on pills.
A couple of hours later on the same day, local police found Kuizon's body in a wooded area near a middle school in Murphy. She had hanged herself.
A missing child report had been filed for Kuizon on Jan. 30.
The two teens reportedly knew each other and were friends. Investigators are trying to determine whether their deaths may have been the result of a suicide pact, according to CBS DFW.
"If that happened that there was some sort of pact, we need to know because it may lead to further tragedies such as this one," city spokesman Celso Martinez said, according to the Dallas Morning News.
"We don't know if it was but we don't want to discount the possibility offhand," he added.
Police found no signs of foul play in either of the deaths.
Classmates of Sachdeva and Kuizon said they were shocked to learn what had happened.
"Both the girls were AP students and both were involved in lots of clubs so its affecting a lot of people," one student who knew the girls told CBS DFW.
More than a hundred people met with grief counselors on the Plano East High School campus over the weekend, and students have taken to Twitter to commemorate the deceased teens.
North Texas psychologist Sylvia Gearing said teen suicides can have profound effects on peers.
"Kids are vulnerable to the actions of others," she said. "And this kind of behavior is contagious."
Gearing also warned that suicidal teens are not always who they might appear to be.
"One that we really get worried about is what we call the smiling depressant," she said. "They are getting all A's and appear to be doing beautifully in all other areas, but there is an underlying depression that no one knows about."
