German police say a man appears to have used an ax and knife to kill his wife and two children on Saturday night.

Police in the city of Saarlouis near the French-German border say they arrived at the home to find the 47-year-old man heavily intoxicated and sitting next to the body of his murdered wife. The bodies of his 20-year-old stepdaughter and 6-year-old son were found upstairs.

His 40-year-old wife had been killed with an ax, while the stepdaughter and son were killed with a knife.

Police said in a statement Sunday that they arrested the man on suspicion of homicide.

An 3-year-old son was also home when police arrived. He was uninjured in the attack. Police took him to a nearby hospital.
