Alex Tennison

Alex Tennison, otherwise known as "The Willowman", is a character in the "Law and Order: Investigation" series, He is the killer of his abusive mother and acts as the villain of episodes 5-7 of Season 2. He first appears in Season 2, Episode 5.

Alex killed his mother after she caught him and Zane playing in the park at night and started to physically abuse them. He struck her in the head with a rock, pushed her off a bridge, and left a stick figure held together with resin (a substance produced by trees) next to her corpse.

The boys are first interrogated after finding out their mother's address. During the interrogation, you discover a hidden room that contains several paintings depicting the Willowman, a well known urban legend. If you take the premium option to investigate their home further, you discover that both Alex and his mother were prescribed anti-psychotic medication, implying that both of them had mental health issues. Although Alex had originally stayed quiet during the interrogation, he perks up at the mention of the mythical boogeyman and claims that he saw The Willowman kill his mother.

When the boys are later interrogated at the police station, he becomes angry and says that he *is* The Willowman until Zane calms his down. If you choose to indict Alex for the murder instead of Zane (who was trying to protect his brother and take the fall for him), it is mentioned he will be sent to a mental institute.

Trivia

 * If you listen to Dr. Spellman's report in Episode 7, she diagnoses Alex with Bipolar disorder, a mental condition that causes severe mood swings and behavioral changes.
