A father killed his 2-year-old daughter and himself in Cudahy early Friday, mere hours into the new year.

Police received a call around 1:40 a.m. from a woman asking for medical assistance in the 3700 block of E. Whittaker Ave. Officers arrived and found the 27-year-old man and his daughter suffering from gunshot wounds, police said in a news release.

The man was pronounced dead at the scene, and the girl died later at Children's Hospital of Wisconsin.

The man and girl have not yet been named publicly, and no other information was released about the circumstances of the killings.

The Milwaukee County medical examiner's office also is investigating.

Neighbor James Toczyl said he didn't know the family.

"They keep to themselves, he said. "I didn't even know they had a kid."
