The first sign that something was wrong was his discovery of his missing wife's sandals, jacket, headscarf and knife on the forest floor.
The second sign was a heavily bloated snake, encountered by a search party looking for Jahrah the following morning.
"During the search, the team found a giant python, measuring 7m in length, which we suspected had preyed on the victim," the police later said in a statement, which had referred to the victim simply as "Jahrah", in line with the Indonesian custom of going by just one name. "The team captured the snake."
The search team killed the reptile and sliced open its stomach, where they discovered Jahrah's remains intact.
"The victim's body was not destroyed when we found her inside the snake, meaning that she had only been recently swallowed whole," the police said, after they found the reptile near the village of Betara in Indonesia's Jambi province, on Sumatra island.
Non-venomous pythons usually prefer to not attack humans, choosing instead to feed on smaller animals which they secure with a non-venomous bite before suffocating it to death and then eating it.
But occasionally, humans are known to become their prey, too.
Snake conservationist Nathan Rusli, the director of the Indonesia Herpetofauna Foundation, suspects a reticulated python was probably responsible. The species is the only reptile living in the Sumatran province of Jambi that is large enough to have consumed an adult human, he said.
"They are constrictors, so what they do is coil their body around you. They will give you a hug of death. You breathe in and your body gets smaller, it tightens its grip, and you can't breathe out," Rusli explained. "The top and bottom jaw of a snake is connected by ligaments, it's quite flexible. They can swallow prey larger than the size of their head."
Confirmed reports like these are relatively rare, occurring around once a year.
"Most cases are cases of farmers working in rubber and cacao plantations in Sumatra and Sulawesi, most cases occurs at night," Indonesian snake expert Djoko Iskandar, a professor at Bandung Institute of Technology, said. Only extremely long reptiles were able to successfully hunt adult humans, with the smallest Indonesian python known to have been involved in a fatal encounter measuring more than 5.5m, Iskandar said.
Encounters between pythons and humans are becoming more common in Indonesia as people encroach on their habitats, which have come increasingly under threat, snake experts say.
In 2017, a 25-year-old villager on the island of Sulawesi was discovered inside a 7m python, suspected of killing him. The following year, this time on Muna island, a 54-year-old woman checking on her mealie crops was swallowed whole in an area of the country known for its population of reticulated pythons.
Deforestation, which deprives snakes of their natural environment and food sources, is cited by experts as one factor behind the increasing frequency of fatal encounters between the reptiles and humans. Since 2000, Indonesia has lost 18% of its total tree cover, primarily as a result of deforestation, according to recent data from Global Forest Watch.
"If you destroy forest, the natural habitat of these animals, where are they going to go?" Rusli asked. "Especially if an area is fragmented, they'll need to cross human settlements to get to another part of the forest."
Additionally, trash, rats, and domestic animals associated with human life are easy prizes for snakes looking to feed, another attraction posed by the towns and villages increasingly encroaching upon their habitat. The pythons are also more likely to be hungry as a result of more competition from humans for the same food prey.
"It would be good not to demonise the snake too much," Rusli suggested.
