The son of a Chester police officer used his dad's gun to kill the mother of his third child, according to prosecutors. Then he ran back to dad's house, phoned two friends and confessed to killing his two other young children years ago. Within the hour, Aaron Michael was gunned down by his father's fellow officers.
Michael, 29, was questioned in 2005 when his 4-year-old son, Lamar Patrick died, and again in 2007 when four-month-old Alijah Townes died. In both cases, the medical examiners ruled the cause of death as "undetermined" and prosecutors did not have enough evidence to link him to the deaths, but are now re-opening each case.
"[The mothers] were extremely suspicious of the circumstances that led to the death in each case," said Delaware County D.A. G. Michael Green.
Andrea Arrington, 23, was Michael's ex-girlfriend and the mother of his third son. She filed a protection from abuse order against him on July 2. Last week he violated that order when he threatened to kill her. Monday night he went to Arrington's Ridley Township home and shot her more than 10 times with his father's duty pistol, a 40-caliber semi-automatic, according to police.
Arrington died at the hospital.
"She was beautiful to me," said Arrington's mother, Audra Thornton-Arrington. "She was a good girl…and wanted to be in television." Arrington was about to earn her associates degree and was set to attend Temple University in the fall.
Michael lived with his dad, a 15-year veteran of the Chester police force, and that's where police found him just after midnight. His dad was out of town at the time. Michael tried to run out the back door but was stopped by an officer and raised his gun, according to investigators. That's when the officer fired one shot and hit Michael in the chest.
A memorial is growing at the spot where Arrington was gunned down as family and friends grieve her loss. Autopsies will be performed on both the Michael and Arrington.
