Accused San Antonio cop killer marries Houston woman hours before being captured

SAN ANTONIO - As the accused San Antonio cop killer made the customary “perp walk,” he shed light on what motivated him to take the life of a decorated  police detective. A custody dispute regarding his child. Even more bizarre, he took the time to get married to a Houston woman even though  he was the focus of a nationwide manhunt.

“I just wanna see my son,” said 31-year-old Otis Tyrone McKane. He was captured Monday afternoon after an intense 36 hours in the Alamo City.

“I've been through several custody battles. And I was upset at the situation I was in and I lashed out at somebody that didn't deserve it,” he said while being led in handcuffs to the backseat of a squad car.

McKane said he was upset about “society” not letting him see his son.  Why detective Benjamin Marconi was the target still isn't clear.

Marconi, a 20-year veteran on the force, was ambushed outside police headquarters Sunday evening while writing a traffic ticket inside his squad car. That ticket was not for the suspect.

McKane is no stranger to trouble. He has a criminal history with SAPD. Four years ago, he was convicted of assaulting his spouse and spent 60 days in jail.  He was on authorities' radar for Marconi's assassination right after surveillance footage showed him at the building.

The FBI got involved immediately.

“We had assets throughout the country working on leads that were generated through San Antonio police that we ran down,” said Christopher H. Combs, FBI Special Agent in Charge.

McKane had a woman and a 2-year-old with him when he was captured driving the woman's white Buick. In a bizarre twist, records show he and that woman got married at the Bexar County courthouse about seven hours before he was arrested. Despite being the focus of a massive nationwide manhunt, he was saying "I do" to Christian Chanel Fields.

McKane is facing capital murder charges. If convicted, he's looking at the death penalty or life behind bars.

Detective Marconi's family issued a statement:  "At this time, the Marconi family would like to give thanks from the bottom of our hearts for the outpouring of support, prayers and love we have received. At this time, we would appreciate privacy to mourn the loss of a wonderful father, brother, grandfather, friend and - last but not least- a peace officer. Thank you to the San Antonio community and nation as a whole for your support."

McKane apologized to the family, but saying sorry offers little comfort. It's just a relief that no one else was killed before he was caught.
