Requesting help with the two assignments below - any information and  websites.

  Helen Valentine was found deceased in the master bedroom of her upstairs, two-bedroom apartment, at 11:58 AM on Tuesday morning. Upon arrival, the investigators noticed an empty bottle of vodka on the floor of her bedroom, and two shot glasses- half-full with vodka, on the kitchen table. There were also three visible dust footprints on the linoleum floor in the bathroom and kitchen. The television was on and the refrigerator was slightly ajar. Some half-eaten cheese and crackers were located on the countertops in the kitchen, and the smell of bleach was very apparent in the kitchen.
Valentine was found in a prone position, completely nude, with her head towards the foot post of her bed, facing the wall. Valentine's entire apartment was a mess, but there does not seem to be any real signs of struggle. Investigators noticed a few cuts and bruises on Valentine's wrist. After closer examination, investigators noticed a small gunshot wound on her left temple. The weapon was found in very close proximity to Valentine's right side, next to her right shoulder.
The three windows to Valentine's apartment were open and the front door was unlocked. Neighbors provided statements, stating that Valentine was a nudist and liked to flash people who passed by her windows. Investigators also found an apparent suicide note on the computer screen in the second bedroom (the computer was still on, but was in hibernating mode). Valentine's bank check; made out for $1,006.57 to a nudist colony resort and spa, lay on her computer desk.
In the investigator's initial inspection, blood could be seen in the second bedroom and on the windowsill of one Valentine's apartment windows.

1.  Research the types of physical evidence that may be obtained by criminalists at the crime scene where Helene Valentine was allegedly murdered, and identify the section(s) of a forensic science laboratory that might examine this evidence. (4 to 5 paragraphs)

2.  You are the lead investigator at the crime scene at Helene Valentine's home. Do you need a warrant to collect evidence and conduct an analysis of it? Search the Library, Internet, and case law and write a 3- to 5-page paper that states whether or not you would recommend obtaining a warrant and detailing your reasoning. (3 to 5 pages)

Types  of physical evidence
Most evidence can be divided into three broad categories: direct evidence, indirect evidence, and physical evidence. Direct evidence establishes an element of a crime through an eyewitness account, confession, or anything observed (including writings and audio, video, or digital recordings of observations). Indirect evidence is based on inference and deductive reasoning (e.g., a smoking gun indicates the weapon has been fired and is probably linked to the dead body next to it). Physical evidence results from a criminal investigation. Physical evidence is a form of evidence that can help reconstruct the events leading up to and during the commission of a crime. It can be used to associate a suspect with a victim or crime scene, help identify a suspect or verify a witness's testimony, and aid in the investigation so that law enforcement can develop a suspect. Physical evidence is found in many different forms, including biotic (living) and abiotic (nonliving). The former, also known as biological evidence, is a form of physical evidence that originates from a human, animal, or plant (e.g., blood, semen, saliva, hair, nails, fur, leaves of plants, spores, wood). The latter type of physical evidence includes items such as glass, paint, soil, metal, chemicals, poisons, and so on. Many times, these three categories of evidence can overlap: the content of a written confession is direct evidence, the fact tha
