Charges include assault with intent to commit murder. Both men could spend the rest of their lives in prison if convicted.
Investigators say the plan was hatched in March when Rogers learned Latonya Bowman was pregnant with his third child.
Police say it does not appear Rogers offered Mathis any money to commit the crime.
Mathis can be seen on security camera video at a Home Depot in Warren buying duct tape, a rope and gloves the night before the crime, according to police.
Police also say Rogers sent text messages to Bowman while the crime was taking place to try to establish an alibi.
The victim, who survived being kidnapped, set on fire and shot, gave birth to a baby boy Tuesday morning. She was due in three weeks but had an emergency c-section.
Warren Police say the 22-year-old victim was attacked Saturday morning.
The victim told police she and her ex-boyfriend had just returned from a drive-in movie in Dearborn when she dropped him off at a home on Sherman Street in Warren. Rogers lives there with his mother, current girlfriend and Mathis.
Bowman says she and Rogers pulled into the garage and then got out of the car. The garage door then suddenly closed.
“The next thing she knew she was grabbed by the throat and a gun was put to her head,” said Warren Police Commissioner Jere Green. “She was ordered to the ground.”
Green says duct tape was placed on her mouth, eyes, and wrapped around her hands and feet.
The suspect then drove her around in her Saturn Vue for about ten minutes before stopping in an alley in Detroit. That was near I-94 and I-75.
Then the man said two things.
“He said ‘you know why this is happening’ and then he asked her about how far along she was,” says Commissioner Green.
The woman, who was nine months pregnant, says she felt liquid poured on her, then heard a match strike and then she was on fire.
“She was able to get out of the car and start rolling on the ground, trying to put the fire out,” Green says. “And when that happened, two shots were fired and she was struck once in the back.”
She played dead, and the man took off.
