Police were called to a home in the 1900 block of Johnston Avenue in San Jose Friday night to find two injured women, one of them fatally injured with a "machete-type weapon." The dead woman has been identified as 65-year-old Yvonne Marie Kirk, and the second woman, who was later arrested in the killing, has been identified as Sagal Mohamod Sadiq.

Sadiq was treated for her wounds and released from the hospital, after which she was booked on murder charges.

The relationship between the two women has not been revealed, nor has a possible motive for the killing.

This was either San Jose's 39th or 40th homicide of 2011, depending on who you ask. In any event, it's a 15-year high for murders in San Jose.
