A day that started with happy news of a healthy pregnancy for a young couple ended in tragedy.

Riante Hicks was driving his pregnant 23-year-old fiancee home from a hospital checkup on Tuesday when he says a blue van began to merge into his lane on westbound I-94 near Morang in Detroit.

The 25-year-old swerved his SUV onto the shoulder to avoid hitting the van, struck a pole and the vehicle flipped several times.

Shardae Homesly, who was not wearing a seatbelt, was ejected from the vehicle and her 7 1/2-month-old fetus fell from her ripped-open body, Michigan State Police Sgt. Linda Mys told the Detroit Free Press.

"Troopers at the scene realized the grotesque scene in front of them," Mys said.

Mother and child were rushed to St. Johns Hospital, where they had just left, but neither survived.

"That was my life right there. He was my life, also. But, I mean, I just loved her. She was amazing. (I'll) never find another person like that," Riante Hicks told Fox 2.

Now, police are looking for the driver of the blue van that Hicks swerved to avoid.

"I suffered a great loss today. So, if anybody out there (knows) anything, please just come forward and say something," Hicks said. "It means a lot at this point. It means everything to me right now."
