Residents sleeping in cars a day after Puerto Rico suffers 6.4 earthquake

A day after Puerto Rico’s most powerful earthquake in more than a century, scientists warn it’s impossible to predict when the tremors will stop. The 6.4 magnitude quake leveled buildings and killed at least one man in the southern part of the island Tuesday, leaving more than 300 homeless. “CBS This Morning” lead national correspondent David Begnaud reports from Ponce, Puerto Rico.
