Search Underway for Mountain House Teen Arnav Sharma After September 16 Disappearance

 A search is underway for Arnav Sharma, 18, of Mountain House, California, after his family reported him missing following a visit to a friend in Livermore on Wednesday, September 16, 2026. His disappearance has prompted concern among relatives and others who may be able to help establish his whereabouts. For the Sharma family, the uncertainty has continued since their last confirmed communication with him that afternoon, leaving them focused on finding reliable information and bringing him home safely. The family’s appeal is centered on verified sightings and practical leads rather than assumptions, reflecting the need for accurate information while the search remains active and careful for everyone involved today.

According to a missing-person flyer shared by his parents, Giri Sharma and Reena Sharma, Arnav was in the Livermore area after visiting a friend. The family said he had reportedly been at Las Positas College and planned to use public transportation to return to Mountain House. His last confirmed communication with his family occurred at approximately 12:30 p.m. on September 16, according to the details provided by his parents.

Authorities were notified after Arnav could not be located. The Livermore Police Department was made aware of his disappearance, while information provided by the family indicated that his last known phone location was recorded at approximately 1:47 p.m. near Johnstown Road and Owen Drive in Pleasanton. A phone location can help establish a possible lead, but it does not necessarily establish a person's exact movements or whereabouts after that point.

The timeline gives investigators and those assisting the family several points from which to work. Arnav was reportedly connected to the Las Positas College area in Livermore, had planned to travel home by public transportation, and was later associated through a phone location with an area of Pleasanton. The available account does not establish what happened between those points or where he may have gone afterward. Those unanswered questions are now central to the effort to locate him.

For his parents and other loved ones, a missing-person case brings a particularly difficult kind of uncertainty. There is no confirmed explanation for why Arnav has not returned home, and the supplied information does not establish that he has been injured or harmed. Until authorities provide verified findings, speculation about what may have happened should not be treated as fact. The priority remains determining his whereabouts and helping ensure his safe return.

Family members have been working to spread awareness and gather useful leads since Arnav disappeared. They are asking anyone who may have seen him, interacted with him, or noticed something relevant in Livermore, Pleasanton, or along his expected route home to provide details to authorities. Accurate observations, rather than speculation, can be especially valuable during an active missing-person search because even a small verified detail may help investigators reconstruct a person's movements.

Arnav remains missing, and his family continues to hope for his safe return. The circumstances surrounding his disappearance remain unclear, while authorities and those close to him work to establish what happened after his last confirmed communication. For now, the most important details are his age, connection to Mountain House and Livermore, reported presence near Las Positas College, and the later phone location in Pleasanton. Anyone with credible information should contact local authorities and allow investigators to assess the lead.
