Homicide Cleanup
Once the investigation ends, contaminated materials, blood and tissue are cleared during homicide cleanup.
See homicide cleanupGet blood, body fluids, fingerprint powder and odor removed from a home, apartment, rental or business in Saint Helena once police release the property. Most crime scene cleanups take one to three days.
Crime scene cleanup, also called forensic cleaning or trauma scene cleanup, is the removal of blood, body fluids, tissue and contaminated materials after a violent crime, then disinfection and odor removal so the property is safe to use again.
The investigation comes before any cleaning. Detectives, police and the medical examiner remove the deceased and collect evidence, but cleanup is not part of their role. After release, responsibility for the scene passes to the family, landlord or property owner.
Crime scene cleaners, also called forensic cleaners or a forensic clean up crew, treat every drop of blood as infectious. They trace how far it traveled, remove what cannot be disinfected, clean and treat every surface, and haul the hazardous materials away under medical waste rules. It is a form of biohazard remediation, and the cleanup process covers these steps from start to finish.

You can call during the day or overnight, and unmarked vehicles help keep the situation private from neighbors.
Crews put aside photos, papers and meaningful belongings for you to examine before any disposal.
Photos, scope and waste records are ready for insurance companies and landlords, so you can move forward.
You hear the cleanup steps and what affects the price before any work starts, so you can make the right decision for your family.
Any violent event that leaves body fluids or blood behind calls for crime scene cleaning services. Common examples include:
After a standoff, pepper spray or tear gas residue can remain on fabric, walls and HVAC ducts.
Floors, furniture and walls can have blood and tissue in several rooms.
Family members can avoid seeing the scene when cleanup is done privately.
A fall can leave blood on walls and ceilings, with saturation reaching carpet and subfloor.
The first hours matter for your health, your insurance claim and the final cost. Before the cleanup technicians arrive:
Call (888) 440-9227Published cost guides put most residential crime scene cleanups between $1,500 and $7,500. Most crime scene cleanup companies price by the job, not the hour. A small area of surface blood can cost less, and scenes where blood reached the subfloor or several rooms can pass $10,000. The final price is set after the on-site assessment.
These ranges come from published national cost guides, not from a site visit. You learn what your property will cost after the on-site assessment and before any work begins.
Ask about cost: (888) 440-9227Check the homeowners or renters policy that applies to the property. It may include crime scene cleanup when an event is classified as accidental and sudden, and you may owe a deductible.
In rental units and common areas, the owner usually arranges and pays for crime scene cleanup.
Your homeowners or renters policy terms determine coverage following a violent crime. Make the event report quickly, then write down your claim number.
Ask whether biohazard cleanup is covered, whether you can choose the cleanup company and what photos or records the adjuster needs.
The Maryland Criminal Injuries Compensation Board, part of the Governor's Office of Crime Prevention and Policy, lists crime scene cleanup among eligible expenses for crime victims. Insurance is usually checked first.
Although no two crime scenes are alike, each remediation process uses one safe sequence. The crime scene cleanup process moves in that order from an initial walk-through through the final inspection.
Before starting, technicians join you or your representative for an inspection, take photos and confirm the planned work.
The crew wears complete personal protective equipment and seals the affected area with negative air and plastic sheeting.
Saturated drywall, carpeting, padding, mattresses and furnishings are removed, placed in bags and sealed for medical waste disposal.
Technicians clean every surface before using hospital-grade disinfectant registered by the EPA for its required contact time.
Air scrubbers, hydroxyl generators or ozone treat odor at the source, and HVAC vents are checked.
Sealed containers go to a permitted medical waste facility with the paperwork that tracks them.
ATP testing can be used to check surfaces, while photographs and records support your insurance claim.
After cleanup, replacement drywall and flooring may be installed by your contractor or the insurance company's vendor.
You can call anytime. A specialist in crime scene cleanup takes your call, explains each step and agrees on a start time with you.
Blood and bodily fluids can be hazardous to your health, and contamination often extends beyond the visible area.
Hepatitis B, hepatitis C and HIV can be present in blood. Despite dry-looking blood, hepatitis B may survive on surfaces for at least seven days, according to the CDC.
Cleaning the place where a loved one was hurt is a heavy burden. That burden alone leads many families to hire professional crime scene cleaners.
Saturated items count as regulated medical waste. They must be taken to an authorized treatment site instead of a dumpster or household garbage.
Can you clean it yourself? For a few drops of blood that are fresh and limited to a non-porous hard surface, use gloves plus an EPA-registered disinfectant. If blood touches fabric, wood, carpet or drywall, or spreads beyond visible edges, you need professional cleanup.
For most crime scene cleanups, time at the property is one to three days. A recent scene with a small affected area can take a day, while structural removal at a heavy scene can extend the work to two to five days.
| Scene | Typical time on site |
|---|---|
| Light scene, one area | Often one to two days |
| Typical scene, one to two rooms | Often one to three days |
| Several affected rooms or a subfloor removal | Often two to five days |
The source must be removed before the odor can be addressed. Spraying fragrance on tissue or blood masks the smell for just a few days.
After the contaminated materials are gone, the cleanup team can use HEPA air scrubbers to capture particles, hydroxyl generators that are safe to run while people are present, and ozone treatment in empty rooms for stubborn odor. Thermal fogging reaches odor in fabrics and wall cavities, and HVAC ductwork is checked so smell does not travel to other rooms.
Federal rule 29 CFR 1910.1030 sets requirements for protective equipment, training and handling whenever workers can be exposed to blood.
A disinfectant for blood should carry EPA registration and stay on each surface for the complete labeled contact period.
Maryland calls this special medical waste, which can include blood-soiled articles. Maryland Department of the Environment rules control how it is handled, transported and treated, so it cannot go in household trash.
Maryland uses a statewide system run by the Office of the Chief Medical Examiner, part of the Maryland Department of Health, which investigates sudden, violent or suspicious deaths. Cleanup starts after police or the medical examiner release the scene.
