DNA is everywhere

Vincent Brothers' DNA was found in a glove tip at the house where his family was killed, but unidentified people left DNA on many items at the house, a criminalist testified Thursday.

Kern County Regional Crime Lab supervising criminalist Brenda Smith found Brothers' DNA mixed with DNA from at least two other people on the tip of a glove.

For instance, the base of a phone had DNA from Marques Harper, the couple's oldest son. But it also had DNA from someone other than the Harper family or Brothers.
