Police are reporting that an arrest has been made in the late-morning murder of 39-year-old Yvette Saunders, a mother of six who was shot in the chest outside her home near 52nd and Kingsessing on the day before Mother’s Day.

The Philadelphia Inquirer has a short, heart-wrenching story about the shooting. The Inquirer‘s Mike Newall reports that Saunders was shot outside her home on the 5200 block of Reinhard Street trying to protect her 18-year-old son, the intended target of the alleged gunman.

Newall reports that Isaac Porterfield, 22, of the 500 block of North Vodges Street, has been charged in the killing. Police say Porterfield turned himself in.

The shooting was a result of a dispute between Porterfield and Saunders’ son, who accused a friend of Porterfield’s of beating up his girlfriend.

Saunders’ son was not hit in the shooting.
