These houses, located on Church Avenue in McKees Rocks, have a fascinating history! In 1908, the Pittsburgh Press reported that "pretty" 17 year-old Nelly Yost, a singer, had been murdered by her older admirer and next door neighbor, Samuel L. Gardner. Gardner was a former McKees Rocks borough engineer, 56 years-old, and married! They lived side by side in the two houses to the left in the picture. Nelly Yost was shot three times by Gardner before he shot himself (both died) at the foot of the stairs in the house second from left.
