Wichita police have arrested a man for killing his girlfriend in the northwest part of Wichita.

At about 2:00 a.m. Tuesday a man called 911 dispatchers, telling them he'd harmed his 22-year-old girlfriend. When police arrived at an apartment complex in the 1900 block of N. Amidon, they found the man with a knife; he was taken into custody and booked into jail for one count on suspicion of first-degree murder.

The woman was found dead inside the apartment from multiple stab wounds.

There have been 24 homicides in Wichita this year in 25 weeks; this is the third domestic-violence murder case this year.
