UPDATE: Police crews continued their search on the Schuylkill River Monday.
More than three weeks after his disappearance, officials found the keys of missing college student Shane Montgomery.
The Garden State Underwater Recovery Unit, a volunteer diving recovery team, discovered the 21-year-old West Chester University student's personal keys in the Schuylkill River after searching for four and a half hours Sunday. No further evidence has been found however.

The Roxborough native was last seen early Thanksgiving morning as he left Kildare's Irish Pub along Main Street in the Philadelphia neighborhood of Manayunk.
Pings from his cellphone put him within a mile of the bar within an hour of his disappearance and surveillance video shows the West Chester University student walking toward the Manayunk Canal and Schuylkill River. Despite many searches on land, in the water and from the air, there have been no strong leads as to where Montgomery went.
Each day without Shane has been wearing on his family, said Kevin Verbrugghe, Shane's uncle.
"We’re not holding up well," Verbrugghe said.
Ongoing search efforts, including the use of sonar and underwriter cameras in a search of the Schuylkill River, have brought about few clues for Shane, who was last seen walking toward the Manayunk Canal.
"The prevailing theory is that he went into the river and where is he now? Tides change and there’s all kinds of debris under there," FBI Supervisory Special agent J.J. Klaver said Thursday.
Debris could have trapped the missing college student's body underwater, he explained.
A reward for information that leads investigators and the family to Montgomery still stands at $65,000. Friends and family continue to support the search efforts on their own as well.
Anyone with information is asked to call Philadelphia police at 215.686.TIPS.
