In the predawn hours of August 23, 2009, Toni Sharpless (born December 27, 1979) and her friend Crystal Johns left a party at the home of Philadelphia 76er Willie Green in Penn Valley, Pennsylvania, United States. Not long after leaving, Johns suggested to Sharpless, whose erratic and combative behavior had led Green to ask that they leave, that she was not sober enough to drive; in response, Sharpless pulled over and told Johns to get out, which she did. Sharpless has not been seen since then.An early theory, that she might have accidentally driven her car into the nearby Schuylkill River, was discarded when searches of the river were fruitless. An apparent break in the case came two weeks later when an automatic license plate reader recorded her 2002 Pontiac Grand Prix's plates among parked vehicles in Camden, New Jersey, across the Delaware River from Philadelphia. There had been other reported sightings of Sharpless in Camden, but police there were unable to locate the vehicle or find any information about where it had been found.In 2013, the writer of an anonymous letter sent to Eileen Law, a private investigator handling the case, claimed that he had been hired to take the Pontiac to a shop in the Boston area in exchange for $5,000 in cash and the Grand Prix's license plates after Sharpless was killed during a confrontation with a Camden police officer. The writer did not personally know of any details about what had happened to Sharpless but included in his letter the number of her cell phone, missing along with her, and the last five digits of the car's vehicle identification number, information that had not been made public. Both were correct.Police dismissed the letter as a hoax despite the details, but Law, whose theory is that Sharpless is alive and being held captive by human traffickers, believes it was genuine and continues to investigate. In 2011, the Investigation Discovery channel's series Disappeared devoted an episode to the case.

Mill Creek is a 6.6-mile-long (10.6 km) tributary of the Schuylkill River in Lower Merion Township, Montgomery County, Pennsylvania, United States.The north branch arises from a number of sources north of Lancaster Avenue (U.S. Route 30) in Villanova. The south branch arises near Ardmore, and has Trout Run as a major tributary. The two branches merge near the intersection of Old Gulph Road and Mill Creek Road, and the lower creek flows east to join the Schuylkill River just upstream of the Gladwyne interchange of the Schuylkill Expressway (Interstate 76 exit 337) and the Flat Rock Dam.Dove Lake is located beside the north branch of Mill Creek, just upstream of where Old Gulph Road crosses the creek at a ford. The ford has a gate, which is frequently closed when high water makes crossing it dangerous. The lower creek has some historic mills and related buildings on Mill Creek Road and nearby Rose Glen Road.Mill Creek Road follows the south branch of the creek from Montgomery Avenue near Ardmore to Old Gulph Road, and follows the lower creek to River Road by the Schuylkill River. The road is mostly on the right bank, with two crossings near the junction with the north branch.

The Flat Rock Tunnel is an active railroad tunnel located on Norfolk Southern's Harrisburg Line near Manayunk, Pennsylvania, United States.

In 1858-9 the Flat Rock and Black Rock Tunnels were widened to accommodate the wider rolling stock from the Lebanon Valley Branch. The spacing between the tracks was increased from 4 feet (1.2 m) to 6 feet (1.8 m). The widening of the tunnel was the first project to employ electric detonation of multiple explosive charges.
