For a fourth consecutive day, police, gendarmerie units and dozens of volunteers are out in the countryside of Varna province looking for 11-year-old Natalia Asenova, who disappeared from the village of Konstantinovo, just south of Varna, in the early hours of Tuesday 30 June. The effort is now concentrated on the fields around Yunak and Barzitsa, two villages roughly 30 kilometres from her home, and so far nothing has been found that investigators can confirm.

Investigators suspect Asen Simeonov, a 40-year-old former partner of Natalia's mother, of abducting her. Novinite, the Sofia News Agency, reports that search teams worked through heavy rain and difficult terrain overnight with drones and thermal-imaging equipment, and that units were still deployed across the area on Friday morning.

Where the Search Has Moved, and Why

The operation began around Konstantinovo, a village in Varna municipality, but shifted sharply inland after reported sightings near Provadia, the small town set in a karst gorge that anchors the western end of the province. According to Novinite, plans to restart searching at around 10 p.m. changed when several witnesses reported what looked like a man travelling with a young girl in the fields near Barzitsa; officers, gendarmerie and volunteers then worked the ground between Barzitsa, Bozveliysko and Tsarevtsi until well past midnight, and came back with nothing they could confirm.

Investigators now believe the pair headed for the Yunak and Barzitsa area after the abduction, and volunteers make the sobering point that anyone walking since Tuesday would have had ample time to cross that stretch of country from Konstantinovo. Police have also tried to seal off parts of the zone to cut off an escape, so far without success.

Anyone who has driven the back roads between the coast and Provadia will know how quickly the tarmac gives way to field tracks, scrub and patches of woodland out there. It is easy country to disappear into, and the searchers know it, which is why the drones and thermal cameras have been doing so much of the night work.

A Suspect Police Believe Knows How to Evade Them

One reason the operation is proving so difficult, people familiar with the investigation have told Novinite, is that Simeonov has done this before. During a previous large-scale police search he reportedly stayed hidden for several days, sheltering in abandoned buildings and following the hunt for him through radio and television broadcasts. Police also believe he is capable of going for long stretches without regular food or water.

That history explains a detail worth understanding if you are following the case locally: investigators are deliberately withholding operational information so that nothing useful reaches him. Do not expect a running commentary from the authorities. The silence is a tactic, not a sign that the search has stalled.

What the Family Says Happened

Natalia's mother has described the night of the disappearance in a televised account. She alleges that Simeonov got into the house before dawn as the family slept, that he tied her up and beat her, and that her arm was broken in the assault. "He threatened to kill me if she didn't go with him," she said, and the frightened child left with him.

Relatives say Natalia has managed to telephone a family member twice since she was taken. Both times, they say, she asked a single question: "Is my mother alive and safe?"

Family members have also said Simeonov is carrying a knife. Investigators have not publicly confirmed that, but it shapes the practical advice below all the same.

The Restraining Order That Was Lifted

Natalia's sister says a protection order against Simeonov was once in force but was later lifted. Why it was withdrawn has not been explained, either by the family's account or by the authorities, and it is a question that will deserve a proper answer once the search is over.

Organisations that support victims of domestic violence note that where threats or abuse are involved, the victim's own testimony can be enough to impose a protective measure and to keep it in place. That makes the lapse in this case all the more difficult to understand from the outside.

If You Are in the Area

The search corridor runs through the villages between Varna's southern hinterland and Provadia, countryside where a fair number of British expats have put down roots. If you think you have seen the pair, or anything that might matter, call 112, Bulgaria's single emergency number (our health guide keeps the full list of emergency contacts). Note the time, the exact place and the direction of travel, and let the professionals take it from there.

Given the family's warning about a knife, unconfirmed though it is, do not approach or challenge anyone yourself. And if you want to help on the ground, join the organised volunteer effort rather than heading out alone; the teams are coordinated with the police precisely so that sightings reach the people who can act on them.

As of Friday morning the teams were still out around Yunak and Barzitsa, with the recent witness sightings the best leads they have.
