A different approach is to read the file as records separated by a blank line. Store the data into a hash for each record, then print out only what you need. One benefit is that this method is independent of the order of the lines of the input.

use warnings;
use strict;

$/ = "\n\n";
while (<DATA>) {
    my %data;
    for my $line (split /\n/) {
        my ($k, $v) = split /\s*:\s*/, $line;
        $data{$k} = $v;
    }
    print "$data{'First Name'} $data{'Last Name'}\n" if $data{Location
+} eq 'Central USA';
}
