Missing Princeton student Misrach Ewunetie found dead

Police have recovered a body in the search for 20-year-old Princeton University scholarship student Misrach Ewunetie, six days after she vanished on her way home from an event.

Police in Simi Valley, California, are searching for Rachel Castillo, a 25-year-old mom of two, who disappeared Thursday evening.

Simi Valley police initially responded to Castillo's home Thursday evening "for a call of suspicious circumstances" and found "a significant amount of blood located in her" residence.

Now, authorities are looking for Castillo, whom they believe to be "at risk." She is described as a 5-foot-2 Hispanic woman, weighing 105 pounds, with brown hair and brown eyes.

Castillo is studying to become a therapist and lives with her two young children in the same house as her sister, Emily Castillo, who saw blood as soon as she entered their home on Thursday evening, according to ABC 7 Los Angeles.

"As soon as I saw the blood, that's when I realized something wasn't right," Emily said. "So I called my mom to let her know to come over, and then I immediately called 911."
