Duplex Shooting: Six Officers, One Kicked Casing and a Two-Hour Road Deadline
At 02:10 a 911 call reports gunshots in a 1,100-square-foot duplex unit. First responders find a 27-year-old man on the living-room floor with three gunshot wounds; he is transported in critical condition. Six patrol officers have been inside for 40 minutes. One kicked a spent casing while checking for a suspect, one used the bathroom and flushed, and one opened the back door for a K-9 unit that tracked through a blood trail running from the front door to the kitchen. A silver sedan believed to be the suspect's is parked in the driveway with the driver's door open. The street is a four-lane arterial and the watch commander wants it reopened within two hours. The victim's elderly neighbor, who lives in the adjoining unit and is on supplemental oxygen, is at the tape asking to retrieve her medication. A news van has parked across the street. The detective arrives in 25 minutes and the only other technician is 40 minutes out.
1. Establish the scene: define the perimeter, set entry control and a scene log, and explain how you handle the six officers and their movements.

Perimeter Treat the unit as the primary scene and include the porch, the front walk and the driveway, because the blood trail and the abandoned sedan sit inside the logical boundary. Use existing physical barriers (the duplex wall, the fence) where they exist, and tape where they do not. Do not extend the perimeter so far that you cannot guard it with the people you have.
Entry control One entry point, one exit, both staffed. Start the scene log at the tape, not when the detective arrives, and record the officers already inside retrospectively with estimated times and the reason for entry. Write the log on a form with name, agency, time in, time out, purpose, and signature.
The six officers
- Do not let anyone straighten up, close a door, or replace the casing.
- Photograph the casing where it lies now, and record the officer's account of where it was before he kicked it. Do not stage a re-enactment.
- Interview each officer separately and have each write a supplemental statement covering exact movements: the bathroom use and flush, the back door opening, the K-9 path.
- Request the K-9 handler's report; the dog's track through the blood trail both destroys a pattern and creates transfer, and that has to be in your report before the defense raises it.
- Check the bathroom as a possible destruction-of-evidence site.
Framing Document contamination as fact, not as something to minimize. A truthful record of officer movement is far stronger than an incomplete one that collapses under cross-examination.
2. Is the sedan a separate scene? Sequence your processing with one technician for the first 40 minutes.

Yes, a second scene It gets its own scene log, its own entry control and its own item-number series, even though it sits inside the outer perimeter. Treat it as linked but distinct: same incident, different packaging and different contamination risks.
First 40 minutes, one technician
- Joint walk-through with the detective: no touching, just orient, identify hazards, and confirm the boundaries.
- Exterior overall photography and video of the building, the street, the porch and the car in place. The car is exposed to weather and to passers-by, so photograph it early.
- Photograph and document the blood trail from the front door to the kitchen before anyone else walks it, and record the K-9 path across it.
- Interior photography in a fixed route, clockwise from the entry: casing, victim's location, weapons, casings and bullet defects.
- Only then start collection, beginning with the most perishable and most probative items.
The car Photograph it before it is moved. Swab likely touch-DNA surfaces and process for latent prints and any blood or tissue on the exterior. If you cannot finish before the road must reopen, have it towed to a secure facility, sealed, with a chain-of-custody entry for the tow and the storage location. Get a warrant if the car is not clearly within a lawful search authority before you process it.
Why this order Photography is irreversible in the sense that the scene will never look like this again; a car can be processed later under cover. Documentation that waits is documentation lost.
3. How do you handle the neighbor, the media, and the watch commander's two-hour road deadline?
Read the worked answer
Neighbor on oxygen Do not let her inside. Ask what she needs, write the list down, and retrieve the medication yourself with an officer as witness, photographing nothing medical and logging what left the scene and when. If her oxygen supply is a medical issue, confirm it is adequate or call EMS. Offer to contact a family member. Document the request, the consent and the retrieval.
Media No statement, no confirmation of names, no speculation about the suspect. Refer them to the public information officer. Keep the news van behind the tape, and do not let a camera operator set up where they can see into the unit. If the PIO is not available, say only that the investigation is active and give the PIO's contact.
Road reopening Two hours may be workable, but not by skipping steps. Options:
- Close only the lanes you need and keep a safe corridor for traffic, preserving the yard, driveway and unit.
- Ask the detective and watch commander to put the decision and the reason in writing, with the time and the name of the person who made it.
- If the fleeing path is likely to contain evidence (a dropped item, a weapon, a shoe print), do a documented visual search of the route before traffic resumes.
Never trade away the interior scene for traffic. The unit will be there tomorrow; the road will not.
