The female all the way to the left is the mom named Grace, when arrived at the crime scene she was eating an apple. The man next to her is the dad named Luis. Luisanna is the one wearing the brown coat she is the middle child lives away in college.
The last sibling is the youngest named luisandra, the victim and her are always arguing about everything and she has a bandaid when we interviewed her. My theory is that Luisandra did it because we found blood at the crime scene and she had a bandaid.

Watson and Crick Model found that the shape of DNA was like a twisted ladder. It was called a double helix, DNA is the recipe for making up every living thing.
The first technique to to analyze evidence is DNA purification and extraction. The goal of this experiment is to be able to see our DNA
