POTTSTOWN, Pa. (AP) — A man with a previous conviction in a fatal crash allegedly struck and killed a Pennsylvania teen then conspired with his girlfriend to cover up who was driving.

Police say 43-year-old Robert Norman Sitler Jr. was behind the wheel of a truck that fatally struck 16-year-old Timothy Paciello Jr. last month in Lower Pottsgrove Township.

Sitler and 42-year-old Denise Dinnocenti allegedly lied about who was driving and told Dinnocenti’s children, ages 11 and 13, to say Dinnocenti was behind the wheel.

Investigators say the Collegeville couple admitted they lied because Sitler, previously of Florida, pleaded guilty to manslaughter in a 2004 crash that killed an Alabama county commissioner.

Sitler was jailed Monday on $1 million bail while Dinnocenti was released. A phone listing for her couldn’t be located.
