Confession Video Up Next In Seneca Murder Trial

Posted by wlpo on February 16, 2012

DNA evidence dominated testimony Thursday morning at the Keith Mackowiak murder trial.  Forensic Scientist Dave Turngren testified that jean shorts taken from Mackowiak after the Twardowski murders had the DNA of Al Twardowski.   Mackowiak’s and Twardowski’s DNA were also detected on a torn shirt cuff.

As for the alleged murder weapons, Turngren says they found Al Twardowski’s DNA on a shovel but there wasn’t enough evidence left on a hammer.

Mackowiak is accused of killing Twardowski and his wife Catherine in July 2007.

The last prosecution witness, lead investigator Detective Dave Guinnee is testifying Thursday afternoon.
