Holiday brings carnage to Caln Twp.

Two grisly discoveries within blocks of each other kept Caln Township police busy on Presidents' Day.

In the 200 block of Seltzer Avenue, police were called to a residence after a dispute between a father and son allegedly escalated into bloodshed. Police said Derek Smith, 26, fatally shot his father, Steve Washington, 51. For details, see http://www.philly.com/philly/news/breaking/20120221_Son_shot_dad_in_Chesco__police_say.html

Less than three blocks away, investigators from the Chester County SPCA were called to a residence in the 2400 block of Wayne Avenue. Police requested the assistance after executing a search warrant in an unrelated investigation that revealed evidence of animal abuse.  More information is at http://www.philly.com/philly/news/20120221_Dog_skeletons__witchcraft_books_found_in_Coatesville_home.html
