Planting for Murder: Plants in Arizona That Are Dangerous to You and Your Pets and How They Pertain to Forensic Science

When it comes to murder, there are many ways to go about it. From blunt force trauma to gunshot wounds to strangulation. However, there is one way that can be very effective and can even look accidental. This is through poisoning, more specifically, using plants as a weapon. Now there are many plant poisoning cases throughout the state of Arizona, most being accidental and dealing with animals, but there is also malicious intent behind some. The plants Nerium oleander L. (Oleander), Cycas revoluta Thunb. (Sago Palm), Ricinus communis L. (Castor Bean), Datura stramonium L. (Jimsonweed), and Cicuta virosa L. (Water Hemlock) are known to be poisonous and they are utilized by both murderers and those that wish to attempt suicide. These are also killers of many animals whether that be livestock or the family dog who got into something they should not have. The toxin in these plants breaks down on its own and over time can become untraceable. Most of them will also cause death if not treated within a few hours of ingestion, making them the perfect weapon to use to get away with murder.
