Investigators confirmed human remains discovered last week belonged to an 18-year-old Texas football player who had been missing for two years.

Thomas Brown’s remains were recovered Jan. 9 in Canadian on the side of a road near Lake Marvin, news station KFDA reported.

“We have been advised that the remains of Tom Brown, of Canadian, Texas, has been found off of Lake Marvin Road – near Lake Marvin,” said a press release from Klein Investigations and Consulting, a private firm the Brown family hired. “His remains have been confirmed through dental records.”

Brown was reported missing Nov. 23, 2016, after spending the evening with friends and not returning home, according to the news station. Unsatisfied with police search efforts, his family hired the private firm to investigate the high school senior’s disappearance.

The private investigators said Tuesday the skeletal remains were found by a person who heard their call to “keep a watch on Lake Marvin Road.”

“The person did the right thing – if you see something say something,” the release said. “Although the discovery of Tom’s remains gives some closure to the mystery of his location, there are still questions on what really happened on Lake Marvin Road. And now, a new phase will begin in the investigation, and those whom may know something need to come forward now.”

Brown’s cause of death has not been released.
