It seems that Serenity Sanchez lost her cool and attempted to dice up her boyfriends three year old daughter. Golly, that was Diverse!
The sad part of this story is that Serenity will likely spend less time in jail than the man-hours Police devoted to investigating the crime scene.
I watched TV news coverage of the area five plus hours after the 911 call and it looked from the personnel and equipment on site as they were investigating a mass murder scene. Perhaps they were gathering hair samples from a neighbors dog just as they do in the movies?
This is common today where two wrongs make a right. The Police make a wrong squandering our taxes in gathering worthless data and Serenity's wrong will be not suffering much time in prison, if any.
Oh yes, the right part is Serenity's last name of Sanchez as that will likely work to her benefit with the Court seeing her as being Culturally Challenged in our society and unaware that Baby Stabbing is considered as inappropriate.
