UNIONTOWN, Pa.—An in-home nurse has been charged with child endangerment for allegedly not doing enough to help a southwestern Pennsylvania baby who was born prematurely and died when he began struggling to breathe while she was caring for him.

Online court records don't list a criminal attorney for 42-year-old Jackie Sue Yeagley, of North Union, who, court records show, is also targeted in a pending lawsuit by the parents of Derek Miskanin Jr.

The 7-month-old boy died in the Uniontown Hospital emergency room on Dec. 4, 2011, about an hour after he began having trouble breathing at home. The Fayette County district attorney charges that Yeagley didn't properly respond when alarms on the boy's ventilator signaled he was in distress about 12:20 a.m.

An attorney representing Yeagley in the civil matter didn't immediately return a call Thursday.
