Authorities say former Ravens tight end Todd Heap was moving a truck that ran over and killed his 3-year-daughter in the driveway of their suburban Phoenix home.
The Arizona Republic reported that police say Heap was behind the wheel of the truck when he accidentally struck the girl while moving the vehicle forward outside their home in Mesa on Friday afternoon.
Officials said the girl was taken to a hospital where she was pronounced dead. She was the youngest of Todd and Ashley Heap's five children.
Mesa police said impairment was not a factor.
Heap, 37, was the Ravens' first-round pick in the 2001 NFL draft out of Arizona State, where he was a two-time All-Pac-10 selection. He played for the Ravens through 2010, catching a franchise-record 41 career touchdown passes, then spent his final NFL season with the Arizona Cardinals.
A two-time Pro Bowl selection with the Ravens, he caught 499 career passes for 5,869 yards and 42 touchdowns for his career.
"We cannot imagine the heartbreak and sorrow Todd and Ashley's family feels right now. This is knee-buckling news and an overwhelmingly sad tragedy," the Ravens organization said in a statement. "Our prayers, our thoughts and our hearts are with the Heaps, who have contributed so much to the Ravens and Baltimore community.
"We believe their deep faith and tremendous support from friends and family will help them through this unimaginable time."
There was also an outpouring of sympathy and support for Heap and his family on social media from current and former Ravens.
In 2007, Heap pledged $1 million toward a new pediatric center at what is now MedStar Franklin Square Medical Center. The Todd Heap Family Pediatric Center offers a combined pediatric emergency department and inpatient unit with around-the-clock pediatrician staffing, the first of its kind in Baltimore County.
"We are so deeply saddened by this unspeakable tragedy facing our friend, Todd Heap, and his family," said Samuel E. Moskowitz, president of MedStar Franklin Square Medical Center and senior vice president for MedStar Health. "It was with his kind, heartfelt support in 2007 that we opened the Todd Heap Family Pediatric Center in the emergency department at MedStar Franklin Square Medical Center, where every child who has come through those doors since gently reminds us of the indelible legacy Todd left in our community.
"On behalf of all of us at MedStar Franklin Square, we offer our prayers and support to the Heap family during this difficult time."
The Ravens inducted Heap into their Ring of Honor in 2014. During the induction ceremony he thanked his wife and five children.
"It's all about family," Heap told the crowd. "From Day One, you have welcomed my wife and I, our family, into our community, this city. For that, we'll be forever grateful."
