Patrolman Thomas Lannon was shot and killed at the Junction Depot platform by a subject he had arrested four weeks earlier.

   As he spoke with a friend the suspect approached from behind and opened fire on him without warning, striking him twice.

   The 23-year-old suspect initially fled the scene but turned himself in a short time later. He was subsequently convicted of murder and sentenced to death.

   In 1878, Governor James D. Williams granted clemency four days before the execution and commuted the offender's death sentence to life in prison. After serving nearly 22 years, he was granted parole and died in 1902.

   Patrolman Lannon was single and survived by two sisters.
