( CNN ) -- More than 100 state troopers and deputies searched for the third occupant of a hot air balloon that crashed in flames at a Virginia balloon festival , killing the other two people on board , state police said Saturday . Witnesses captured photographs of the balloon after it drifted into power lines , burst into flames Friday night and crashed into the countryside about 25 miles north of Richmond . Some reported seeing two people either jump or fall from the basket at a dizzying height . The bodies were found about 1,500 yards apart in a heavily wooded area , Virginia State Police spokeswoman Corinne Geller said Saturday afternoon . Two members of the University of Richmond women 's basketball program were among those aboard . Ginny Doyle , associate head basketball coach , and Natalie Lewis , director of basketball operations , were on the balloon , the university said in a statement . It said the medical examiner 's office has not provided official identification . `` As alumnae , classmates and colleagues -- and as invaluable and devoted mentors for our student-athletes -- Ginny and Natalie have been beloved members of our community , '' President Edward L. Ayers said . `` Their leadership and friendship will endure in the lives of so many . '' The search was scaled back at sundown Saturday because of the difficulty of navigating the terrain in the dark . A full-scale effort will resume at daybreak Sunday , police said . The basket and the balloon separated at some point ; neither had been found . Earlier Saturday , Geller told reporters the effort had transitioned from rescue to recovery . The Federal Aviation Administration and National Transportation Safety Board are investigating the crash . `` We will investigate the man , machine and the environment , '' NTSB air safety investigator Heidi Moats said . Weather conditions are one of the elements investigators are looking at , Moats said , though there was no inclement weather at the time and , so far , officials do n't believe those conditions played a role in the crash , Geller said . Thirteen hot air balloons had been soaring on the eve of the Mid-Atlantic Balloon Festival in Doswell , and three were landing close to each other . Two landed safely , Geller said , but as the third balloon descended , it hit a power line , sparking a fire that spread quickly . The pilot began doing his safety maneuvers and `` took every step to manage the situation , '' the spokeswoman said . But then there was an explosion and the basket and balloon separated . Those aboard the balloon pleaded for their lives , witness Carrie Hager-Bradley told CNN affiliate WWBT . `` They were just screaming for anybody to help them . 'Help me , help me , sweet Jesus , help , I 'm going to die . Oh my God , I 'm going to die , ' '' she said . Her daughter told her she saw someone falling out of the basket . Then Hager-Bradley also saw someone plummeting to the ground . Organizers canceled the festival after the accident . How safe is hot air ballooning ? CNN 's Joe Sutton , Mandy Lawrence and Melissa Gray contributed to this report .
Investigators will look at weather conditions . 100 people continue to search through the night for the third balloon , state police say . Two members of University of Richmond 's basketball program aboard . Balloon hit a power line , state police report later .
