Cal Ripken, Jr. (File)

BALTIMORE (August 3, 2012)--Cal Ripken Jr. said Friday his family and police are still searching for answers about the kidnapping of his mother last week, a crime he called "bizarre" and unsettling.

At a news conference Friday in Baltimore, Ripken appealed for the public's help in tracking down the man responsible for kidnapping his mother, Vi, 74, at gunpoint.

Vi Ripken was found unharmed in her car, but Ripken says she remains shaken up and is too traumatized to return home.

The Hall of Fame infielder appeared to choke up as he described a phone call from his sister last week indicating that his mother might be missing.

He said it was "a horrible night."
