A former senior constable, identified in court as Fiona Rosso, testified tearfully about the night Beau Lamarre-Condon allegedly appeared at her home to "say goodbye" three days after the suspected murders of Jesse Baird and Luke Davies. Lamarre-Condon, also a police officer, arrived at Rosso's house on February 22, 2024, in the dark, crying and expressing a desire to see loved ones one last time.
Rosso, who was struggling with her own mental health issues including depression and PTSD, invited Lamarre-Condon inside, fearing he might harm himself. His demeanor then shifted. "He said, 'I've done something bad, I don't want to tell you, I don't want to incriminate you,'" Rosso told the court.
Lamarre-Condon asked Rosso if she had been following the news. When she stated she had not, he instructed her to search for Jesse Baird's name online. Rosso discovered articles detailing the disappearance of Baird and his partner, Luke Davies. Lamarre-Condon then spoke of an "out-of-body experience" and a lack of control.
Outside Rosso's home, a white van was parked. Rosso observed Lamarre-Condon cleaning blood from the vehicle's exterior, eventually resorting to painting over a stain he couldn't remove. He told Rosso he had driven 2.5 hours to a farm with "a girl" to dispose of the bodies. According to Lamarre-Condon, their attempt to sink the bodies failed, and the accompanying female became distressed, leading them to drive back.
Rosso also testified that Lamarre-Condon had previously shown her police-issued firearm at Baird's home. During this time, Jesse Baird accidentally discharged the weapon, firing a round into a wall. Lamarre-Condon admitted to having to patch the hole, a detail Rosso recounted with distress, stating, "I was like, 'Oh my God, you're basically telling me you've just killed Jesse'."
On the following morning, February 23, calls were made from Rosso's phone to Lamarre-Condon's mother and uncle. Rosso maintained she did not recognize these numbers or have prior contact with them. Text messages exchanged from Rosso's phone to Lamarre-Condon's mother, Coleen Lamarre, were read in court. Rosso claimed Lamarre-Condon had used her phone because his was in flight mode. One message from Rosso's phone asked if Lamarre was having a "hot chocolate," to which Lamarre replied affirmatively, with a thumbs-up emoji sent from Rosso's phone. Rosso explained that "hot chocolate" was a code word for a search warrant at Lamarre-Condon's mother's house. Lamarre-Condon reportedly told Rosso about this code when she questioned the "hot chocolate" message.
