Question

Create a Kastle-meyer test crime scene in 3 sentences

Answer 1

Under a harsh flashlight beam, Detective Morales swabbed a dark smear on the hardwood and performed a Kastle–Meyer test, which flashed a vivid pink—suggesting a presumptive presence of blood. The forensic technician recorded the result in the log and emphasized it remained presumptive until laboratory confirmation. Photographs were taken, the swab was sealed in an evidence bag, and the living room was taped off as neighbors watched from the hallway.
