Vallejo Police Department DNA UPDATE for July 1, 2019
"The lab work has turned into more lab work. VPD is still at it. The hunt continues…"
More lab work sounds much better than a dead end.

LCN is an extension of Second Generation Multiplex Plus (SGM Plus) profiling technique. It is a more sensitive technique because it involves a greater amount of copying via polymerase chain reaction (PCR) from a smaller amount of starting material, meaning that a profile can be obtained from only a few cells, which may be as small as a millionth the size of a grain of salt, and amount to just a few cells of skin or sweat left from a fingerprint.
Yes that is great news and now they don’t need a envelope to get the DNA , the letters themselves have enough cells on them.
