COPENHAGEN, Denmark (AP) — Danish police say the remains of a 27-year-old Syrian woman and her two daughters, aged 7 and 9, were found in a freezer inside their apartment in southern Denmark.

Police made the gruesome discovery Sunday in the town of Aabenraa after a relative of the woman told them he hadn't been able to reach her for a few days.

Investigators said Monday that the victims were killed but didn't give any details.

The woman's husband wasn't in the apartment and is now being sought by police.

The family arrived in Denmark in 2015 and received refugee status.
