North Park Police Investigate

LOGAN, Utah -

North Park police arrested a man accused of shaking his baby that later died at Primary Children’s Medical Center on Monday morning. Authorities received a call Wednesday afternoon that a baby was not breathing.

The four-month-old child was transported to Logan Regional Hospital and later flown to Primary Children Hospital in Salt Lake City. Investigators believe the child’s father, Francisco Martinez, shook the child causing serious internal head injuries. The baby was pronounced dead a few minutes after 11:00 p.m on Sunday night at Primary Children’s Medical Center.

Martinez, 36, was booked into jail on Friday on suspicion of Aggravated Child Abuse. A police spokesman said doctors found other injuries on the child that were sustained during previous incidents. At one point, the baby had two cracked ribs and a broken leg. Investigators say they believe Martinez is in the country illegally and the Immigration and Naturalization Service has placed a hold on Martinez.
