( CNN ) -- The combination of a gun and a surprise gone wrong left a beloved 18-year-old track star dead , authorities in Longmont , Colorado , say . The incident happened Friday when Premila Lal and her 12-year-old cousin decided to play a joke on Nerrek Galley , a close family friend , according to Lal 's father . The Lal family had recently moved , and Galley had been keeping an eye on the recently vacated home . Lal and her cousin snuck into the house just before 8 p.m. unbeknownst to Galley , who was playing video games with Premila 's 15-year-old brother , Pranil . Galley and Pranil heard a noise and went to check it out , the brother told CNN affiliate KUSA on Sunday . `` We thought maybe there was an intruder in the house and maybe some people knew we moved , and they were coming to check if we got everything so we started clearing the house , '' Pranil told KUSA . But the intruder turned out to be Premila , who jumped out of a closet as a harmless joke , according to her family . `` The door opened and she kind of , like , screamed and then Nerrek pulled the trigger , '' her 12-year-old cousin told KUSA . Authorities say the family 's description of what happened is consistent with their investigation . `` All the witnesses had consistent statements , '' Commander Jeffrey Satur of the Longmont Police Department told CNN Sunday . A neighbor told CNN 's affiliate KDVR that she saw the group rush out of the home , screaming . Lal was admitted to a hospital and was pronounced dead about an hour later . Galley is being held on charges of reckless endangerment , child abuse and providing a gun to a juvenile because Lal 's 15-year-old brother had access to the gun , police say . So far Galley has not been charged in Lal 's killing . A court hearing was scheduled for Monday . `` We lost a daughter , so we do n't want anybody else to lose their son , you know , especially when it was accident , '' Premila 's father , Praveen Lal , told Denver TV station KCNC . Galley 's attorney was not available for comment Monday . No public statement has been made on his behalf . Pranil told KUSA that Galley `` is devastated right now . '' Police said they do not suspect the involvement of alcohol or drugs . The teen 's death was `` unintended and extremely tragic , '' police said in a statement . Lal was honored at a weekend cross country meet at her alma mater , KDVR reported . Her family described her as an athlete , popular girl and strong student . Longmont is a former farming community at the foothills of the Rockies . More recently , the community of just under 90,000 has developed high-tech jobs . The town was already stunned by a murder-suicide a day earlier . An 80-year-old man shot his 72-year-old wife before killing himself , police say . Before last week , Satur said , he ca n't remember when the last shooting was . `` It 's been a tough weekend . '' CNN 's John Branch and Mayra Cuevas contributed to this report .
