My feeling from what I read is that this was a deliberate act. That is, it was not simply confusion.
I agree! It reminds me of the aunt who undressed her neice and nephew on the highway and marched them accross that highway at night. All were killed. The aunt had mental problems and bi-polar disease but it was known that she had this problem.
Suicide?
Divorce perhaps, work/money.issues?
The evidence would suggest she continued to consume alcohol AFTER getting behind the wheel.
I agree. Suicide/homicide fueled by dutch courage.
