Bryce Laspisa, 19, of Laguna Niguel was reported missing after his 2003 Toyota Highlander overturned near the Castaic Lake main boat launch access road on Friday, Aug. 30, 2013.
Officials on Los Angeles on Thursday reportedly called off the search for Bryce Laspisa, the Naperville college student who vanished last month.
The development came one day after authorities determined a badly burned body found near Lake Castaic a week earlier was not Laspisa.
"We've pretty much exhausted searching in that area," Los Angeles County Sheriff's Department Deputy Johnie Jones was quoted by the Chicago Tribune as saying. "They've found basically nothing. So we're kind of at a standstill."
Laspisa, a 19-year-old student at Sierra College near Sacramento, Calif., vanished Aug. 30 while driving to his family's home in Laguna Niguel. His SUV was found near the lake with his cell phone, wallet and laptop still inside.
His mother said Laspisa told her before he vanished that he'd recently broken up with his girlfriend. That girlfriend was said to be cooperating with authorities.
On Tuesday, a vehicle belonging to Laspisa's father was among those broken into while volunteers searched for the teen.
"A cruel act, but not related to Bryce being missing," Laspisa's mother wrote on the Find Bryce Laspisa page on Facebook. "We cannot thank the kindness of people who caught the thieves as well as replaced our broken window."
Laspisa grew up in Naperville and graduated from Naperville Central High School in 2012. He's described as a white man who stands 5 feet, 10 inches tall and weighing about 160 pounds. He has red-orange hair.
Anyone with information in his disappearance was asked to call 323-890-5500.
The charred body found last week was later identified as Lamondre Miles, 35, of South Los Angeles. Three people were charged in connection with the slaying.
