MOUNTAIN LAKES — Police are asking the public to help find a 15-year-old boy who hasn't been seen in several days.

Thomas Kolding was last at his parents' home Oct. 30.

Authorities believe he took a train from Denville to Newark Board Street Station and then took another train to New York Penn Station, where his trail went cold.

Investigators say Thomas "had a strong interest in traveling to California," the Morris County Prosecutor's Office said Friday.

He was last seen wearing a camouflage jacket, gray skull cap and a black backpack.
