The Daily News story of a daughter who tracked down her father’s killer is a must read. An earlier article from June 10th in the same paper gives more details. The picture below is of Joselyn Martinez and her father a year before he was murdered.

Someone just emailed me about a missing persons case which relatives feel is actually a homicide. That is what people usually believe and they are often right, but in so many cases, there is so little police can do.

So this brief piece caught my eye. Police are asking the public to help identify a man whose body was pulled from the Susquehanna River in Pennsylvania in 1998. It’s such a distinctive face and shape of head, maybe someone will recognize him.

And then there is the story of a, coincidentally, Pennsylvania woman who went missing in 2002 and just returned. I feel for everyone in this case.

I have some links to missing persons organizations, but relatively few as the focus of this site is homicide investigation. If there are any particularly great links I should have, please let me know.

Slate has a crime blog which is run by Justin Peters, Slate’s crime correspondent. Peters posts at least once a day, it looks like, and from what I can tell his writing is well informed and researched.

The second on is Homicide Watch DC. From their site: “Homicide Watch is a community-driven reporting project covering every murder in the District of Columbia. Using original reporting, court documents, social media, and the help of victims’ and suspects’ friends, family, neighbors and others, we cover every homicide from crime to conviction.” There should be something like this in every city.

This is a detail from an undated NYPD photo with the caption, “Lost children.”

From a recent piece in the Wall Street Journal about the homicide clearance rates for 2012:

“When the cold cases aren’t included, the NYPD solved 57% of the year’s 419 homicides, said Paul Browne, chief spokesman for the NYPD.”

He’s referring to the practice of including homicides from previous years that have been cleared this year in the current numbers.

But the percentage of unsolved murders could be even higher than that. A case is cleared when an arrest is made. (There is also something called exceptional clearances. A case is “exceptionally” cleared when the murderer has been identified definitively—by a substantiated confession for example—but the murderer has since died, or is in a country that refuses to extradite him.) But of the cases where an arrest has been made, if it turns out later that they arrested the wrong person, or if the case goes to trial and the person isn’t found guilty, the police department doesn’t go back and adjust the clearance rates. So they will add in murders that were solved, but they do not take out others that weren’t.

Also, I studied the numbers very carefully (my book came out in 2005, so the numbers I looked at were 2003 and earlier) and I found that an unsolved murder has up to 5 – 10% chance of being cleared within one year after it goes cold. After two years, that chance decreases to less than 1%. Not a lot of cold cases get solved, ultimately. If I did the math right, they’re saying they cleared 75 cold cases. That sounds high to me, given the fact that the Cold Case Squad is about a quarter of the size it was when I wrote my book, but plausible. Also, the cold case detectives are not the only ones working unsolved murders, and I don’t know which cases they are including in that number.
