In the first six weeks of 2014, the Travis County Medical Examiner's Office has had five cases of infants dying while on the same sleep surface as one or more adults. Forensic Nurse Leanne Courtney says that's more than in all of each of the previous two years.

"There were four, both for 2013 and 2012; however, the total amount of infant deaths last year were eight, but so far this year, we're creeping up towards that number, so we really want to emphasize to parents and caretakers about the risks of unsafe sleeping environments," Courtney said.
