Dear Joe,

I attended one of your classes in Florida and I have a quick question if you don't mind. Is it better to have a ventilation unit that vents outside of a recirculating system? I looked at purchasing a recirculating system that is heapa, charcoal and ion filtration? Can you advise if one system is better than another?

Thank you,
West Melbourne PD

Dear Jennifer,

Please see the included pdf - Chapter 5, page 24 of our IAPE Standards that discusses this very issue.  

The property room should be ventilated in a manner that controls heat, cold, humidity, and odors. Special consideration should be given to DNA related storage areas to control heat and humidity that tends to degrade biological evidence. Maintaining the room temperature in a controlled environment (60 to 75 degrees, with relative humidity that does not exceed 60% is recommended).
Any area that is used for storing drugs should be independently ventilated in a manner that noxious fumes are removed from the building, and not re-circulated into the building's heating, ventilation, and air conditioning (HVAC) system. The proper design of a drug storage area should include a "negative pressure" ventilation system that changes the air in the storage room approximately 10 -12 CPH (changes per hour).
Heating, air conditioning, and ventilation system duct or registers should be constructed to prevent unauthorized entry into the secure storage area."

Additionally, I included the link for a publication from NIST:

"Adding complex features to the room, such as a ceiling air filtration system, would move this unit in to the "high tech" category. The drying room should be under negative pressure, with 12 to 15 air changes per hour, and the air should be vented to the exterior of the building" (National Institute of Justice and Office of Law Enforcement Standards 1998

Headline of the Month
Green Bay Rape Suspect Captured Using Father's DNA
Date: November 17, 2015

Investigators found a suspect in a Green Bay rape case that officers thought would never be solved. In a story you'll only see on Action 2 News, DNA from the suspect's father led to the big break in the case.
A man police call a "serial rapist" is finally behind bars, accused of sexually assaulting, kidnapping and robbing random women in Green Bay and Milwaukee and attempting to do it again in Minneapolis.
Police used familial DNA for the first time in Green Bay to solve this difficult case.

More than two years ago, Green Bay police began investigating a brutal rape at an east-side apartment.

"The worst-case scenario of the innocent victim being accosted by a stranger in the dark is exactly what this was," Capt. Jim Runge, Green Bay Police, said.

A criminal complaint says the woman "was suddenly struck in the back of her head with a handgun" as she walked up the stairs.
The man forced her into an apartment and repeatedly sexually assaulted her, at one point talking about "killing her," then he suddenly left.

Police collected DNA from the rape kit.

It didn't match anyone in the databank but it did match DNA taken from two other rape cases in Milwaukee a year earlier.

"The Crime Lab picked this case because they thought, OK, we've got multiple offenses, same person. We don't know who it is, so they wanted to try the familial DNA technology, and that's really what put the case together," Runge said.

Just last year, Wisconsin became one of the few states to allow familial DNA testing. "When I say familial, that's just it, a family member who's in the system that has the same genetic material," Runge explained.

Runge says a partial hit came back to a man who turned out to be the suspect's father, whose DNA was collected for an unrelated crime.
The finding led police to the son, 22-year-old Charles Banister, whose DNA, they say, was a perfect match to their crimes.

Banister was already in custody in Minneapolis, charged with breaking into a woman's home there, trying to strangle her in the shower and threatening to kill her before roommates intervened.

He was transported to Milwaukee County, where prosecutors charged Banister with 10 felonies. He's now awaiting trial.

"DNA is a great thing. It doesn't mean we still don't have to do our job of interviewing people, collecting evidence, knocking on doors, documenting. All that still has to be done."

Runge says familial DNA is meant as a last resort for these violent, hard-to-solve cases and requires a special search by the Crime Lab, but it gives them a place to start looking when they're at a dead end.
"I think it's going to help solve some crimes here down the road."

In our last newsletter we discussed a 45-year-old homicide that had it not been for family members asking about the status of the case it may have never been solved. This month we located another interesting article from Green Bay Wisconsin where Familial DNA was used. This is becoming a new trend as several states have allowed this technology to be used.  


I've Got Something 
You Don't Want
MELBOURNE, Fla. - Brevard County deputies have determined that Matthew Riggins, 22, was killed by an alligator in Barefoot Bay lake on Nov. 23 while possibly hiding to avoid law enforcement.
Investigators say that Riggins had told his girlfriend he would be in Barefoot Bay to commit burglaries with another suspect who is now in custody but not cooperating with officials, according to Maj. Tod Goodyear with BCSO.

Deputies responded to calls in Barefoot Bay on Nov. 13 that there were two men dressed in black walking behind area houses, who ran from responding officers. Later that day, Riggins was reported missing to the Palm Bay Police Department.
