Police are continuing their investigation into the tragic deaths of a family of four who succumbed while glamping in the scenic Posong tourist area of Temanggung Regency, Central Java. The victims have been identified as 52-year-old father Muhamad Ali Munawar, his 43-year-old wife Maghfirah, their eldest son Bagas Amar Hakiki (21), and their youngest son Alvino Evan Hakim (16). All four were found deceased, lying on a mattress inside their glamping tent. Initial suspicions point towards carbon monoxide (CO) poisoning, believed to have originated from portable gas equipment used during their stay.
A crucial new development in the investigation reveals that police discovered portable gas stoves inside the glamping tent where the family was found. According to Commissioner Anwar Nasir, Director of General Criminal Investigation at the Central Java Regional Police, the victims had used these portable gas appliances for a barbecue the previous evening. Following the activity, the gas canisters were reportedly brought inside the tent. “The gas cylinders are also being examined. Their position was inside the tent,” Anwar stated at the Central Java Regional Police headquarters on Friday (May 29). While unable to specify the exact number, Anwar confirmed that more than one portable gas stove was found within the tent, indicating a potentially significant source of gas.
Tent Lacked Ventilation
Commissioner Nasir emphasized that deaths due to carbon monoxide (CO) poisoning are highly plausible, especially given that the glamping tent lacked proper ventilation. He drew a parallel to common incidents, explaining, “Yes, many such incidents occur this way. For example, a car engine running with the AC on while the vehicle is stationary and tightly sealed – that’s dangerous. Fatal suffocation often happens in such scenarios.” However, while CO poisoning remains the primary suspicion, investigators are also exploring other potential causes, including food poisoning. “Currently, there are two primary theories: the gas emitted by the portable stoves during the evening BBQ, or food contamination. Samples of food, such as meat, have already been sent to the forensic laboratory for examination,” Anwar clarified. He added, “We are, of course, awaiting the toxicology results from the forensic lab.” Anwar also noted that this incident marks the first time visitors or tourists have died while glamping at the Posong tourist attraction, underscoring its unprecedented nature.
The investigation has also established a timeline of events leading up to the discovery:

Estimated Time of Death and Delayed Discovery
While the precise time of death remains unconfirmed, Temanggung Resort Police Criminal Investigation Unit Chief, AKP Komang Mahendra Deputra, provided an estimated window. “The exact time cannot yet be determined. It likely occurred between the night and early morning,” Mahendra stated on Friday (May 29). He further revealed a significant delay between the time of death and the discovery of the four victims’ bodies. “Yes, that’s correct; there was a 12-hour gap before they were found,” he confirmed, highlighting the prolonged period before the tragedy was uncovered.
Glamping Management Under Investigation
As part of the ongoing inquiry into the family’s glamping fatalities, police have questioned members of the glamping site’s management. Mahendra confirmed that four individuals from the glamping operator have been interviewed as witnesses. “Four people from the management have been questioned as witnesses,” he noted on Friday (May 29). The police are currently awaiting the results of the forensic examination before determining whether any elements of negligence on the part of the glamping management contributed to this tragic incident.
Summary
A family of four, consisting of Muhamad Ali Munawar, his wife Maghfirah, and their two sons, was found deceased in their glamping tent at the Posong tourist area in Temanggung. Preliminary investigations suggest the deaths were likely caused by carbon monoxide poisoning resulting from portable gas stoves used for a barbecue inside the poorly ventilated tent. Authorities are currently examining evidence, including the gas cylinders and food samples, to determine the exact cause of death while awaiting formal toxicology reports.
The victims were discovered on May 27 after glamping staff forced entry into the tent following a lack of response, marking a tragedy that occurred roughly 12 hours prior to its discovery. Police have since questioned four members of the glamping site’s management as part of their ongoing inquiry into the incident. Investigators are working to confirm whether negligence played a role in the event, which is unprecedented for this specific tourist attraction.
