WICHITA, Kan. (AP) — Prosecutors say they might seek the death penalty against a woman accused with three others of killing a Kansas couple last year.

The Wichita Eagle reports 36-year-old Kisha Schaberg was arraigned Wednesday in Sedgwick County District Court, where District Attorney Marc Bennett announced he wanted the option of seeking her execution if she’s convicted.

Schaberg, her son, 19-year-old Anthony Bluml, and two of his friends are charged with capital murder in the Nov. 15, 2013, deaths of Anthony Bluml’s adoptive parents.

Roger and Melissa Bluml were shot in the head as they sat in their car outside their rural Valley Center home. One of the suspects has testified the shootings were part of a plot to gain life insurance, and because of resentment for the couple.
