SOUTH LAKE TAHOE (CBS SF) — Two orphaned bear cubs who watched their mother get hit by a car in June were released back into the wild Thursday.

Lake Tahoe Wildlife care in South Lake Tahoe took in the now 1-year-old cubs from the town of Bieber, a community about 55 miles northwest of Susanville. The cubs were found in good health, and grew substantially in the seven months they were cared for.

The brothers came in weighing near 20 pounds and left about 60 pounds larger.

Since 1978, the Lake Tahoe Wildlife Care center has been helping restore injured and rescued wildlife from nine counties in California and Nevada surrounding the Lake Tahoe region.
