Man arrested for murdering his fiancée’s 2-year-old son, just six days before they married

21-year-old Jagger Jost was arrested Monday, some eight months after he allegedly killed little Vernon Gaylord Sylver Jr. with a brutal punch.

The child hadn’t even been buried before Jost and his fiancée, Tiffany, decided to tie the knot on May 22. And to this day, Tiffany Jost believes her jailed husband is innocent, attributing his death from blunt force trauma to a fall, not a beating.

“I would have killed him myself,” Tiffany told the Philadelphia Inquirer about any concerns of Jagger’s involvement in her son’s death.

Cops were hunting Jagger for almost a year when U.S. Marshals tracked him down Monday in Atlantic City, N.J., where he was staying with an acquaintance. The unfatherly figure was arrested and charged with murder and child abuse.

Little Vernon died of blunt force trauma to the abdomen, according to authorities, allegedly inflicted by a punch thrown by Jagger Jost.

But Jagger told his wife that Vernon landed on his stomach while falling off bricks and sustained the injuries on May 13, 2015. Two days later, Vernon started vomiting and was pronounced dead on May 16.

The couple decided to rush their wedding date because they were so distraught by the toddler’s death, Tiffany told the Inquirer. They married on May 22, nine days before Vernon’s funeral.

Tiffany still stands by her husband, telling reporters that the accused killer loved Vernon like the toddler was his own son.

“I feel like my heart is on fire, because I’m not going to let my husband rot in jail,” she said.
