Black mask Crime Scene
Head towards the current objective marker to reach Lacey Towers and eliminate the police force on the surrounding rooftops or balconies to enter the building safely.
Make a right to open the un-taped door in the back corner and enter Sionis’ Safehouse to approach the two bodies in the next room ahead, then use the Evidence Scanner to analyze both of their hands and target the area beneath the chandelier to start recreating the crime scene.
Reconstruct the crimes for both bodies, the wall beside the steps and the floor in front of them, then turn around to scan the broken desk and follow the red trail out onto the balcony to locate the scrap of fabric.
Scan the indicated spot on the kitchen counter to watch another crime play out, then follow the red trail down towards the floor to find the cell phone and complete this mission.
