A couple of friends who attended a Texas high school together were separately found dead on Sunday in what investigators believe may have been suicides.
The body of Ritu Sachdeva was found in her Murphy home after midnight Sunday. She was 17.
Hours later, the body of her friend Hillary Kate Kuizon was discovered in a wooded area near an area middle school, the Dallas Morning News reports.

A missing persons report had reportedly been filed for Kuzion the night before.
It was not immediately known whether the girls' deaths were related in any way and police did not say whether they had reason to believe they were.
However, CBSDFW reports that no evidence of foul play was discovered at either location.
"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."
As the investigation continued, grief counselors were scheduled to be on hand at lano East High School for students having trouble dealing with the tragic losses.
Another way the students have dealt with the deaths is by mourning for the girls and celebrating their lives on social media as the hashtags #RIPRitu and RIP
"Your an amzing person.PYL is were we cried,laughed,and connected together.God gained an amazing angel!" tweeted Nirali Kotecha along with a photo of Ritu.
