Woman had affair months before murder-suicide

PHOENIX — Authorities say the daughter of a murdered Nevada official had
an affair several months before fatally shooting the woman she was married to
and then turning the gun on herself at their Phoenix home.

A police report released Tuesday concluded that Dallas Kristin Augustine, 32,
had killed Jessie McCaskill, 50, and then fatally shot herself. Augustine was
the daughter of former Nevada Controller Kathy Augustine, who died in 2006.
Augustine’s stepfather, Chaz Higgs, was later convicted of murdering Kathy
Augustine by injecting her with a paralytic drug.

Officers who were called Aug. 27 to perform a welfare check at the home shared
by Augustine and McCaskill discovered their bodies near the front door, with a
handgun between them. There were no signs of a struggle, except for a broken

Friends and family had told investigators that the couple had been together for
about six years and had gotten married in California, but they had disputes in
the months leading up to the murder-suicide, such as the affair that strained
their relationship.

Investigators were told that Augustine had an affair with a woman she met in a
bar and that the other woman tried to extort Augustine under threat of revealing
the relationship. Augustine was kicked out of the house after she told McCaskill
about the affair and expressed suicidal thoughts.

While Augustine stayed at a hotel for a short time, McCaskill burned their
wedding photos, investigators were told. Augustine wrote a confession about the
affair that McCaskill later posted on Facebook.

Friends and family told police that they reunited in hopes of working things
out, but their problems persisted.

The couple planned to move from north Phoenix to somewhere closer to the
Arizona town of Florence, where Augustine was assigned to work after having just
completed training for the Arizona Department of Corrections.
