SAN ANTONIO -- While a manhunt was underway for the man accused of gunning down SAPD Detective Benjamin Marconi, the suspect was busy getting married at the Bexar County Courthouse.

Otis T. McKane, 31, was arrested Monday afternoon just east of San Antonio. During a perp walk, McKane told reporters he was angry about recent court battles.

“I’ve been through several custody battles and I was upset at the situation that I was in, and I lashed out at someone that didn’t deserve it,” McKane said.

When asked by reporters if McKane had anything to say to Merconi's family he said, “Sorry.”

Hours before McKane was arrested, he married Christian Chanel Fields from Houston.

McKane was in Fields' car with a woman and a 2-year-old child when he was arrested on I-10, according to a San Antonio newspaper. It's not clear if Fields was the woman in the car.

Police later found the car seen on surveillance video when Marconi was killed. It is registered to McKane. They are also searching his house for evidence.

"If someone's brazen enough to shoot a police officer in a cruiser, then he would kill anybody. So to get this guy off the street is not just a benefit to law enforcement, but it's a benefit to everybody in San Antonio," said FBI special agent Christopher Combs.

He credits teamwork with McKane's arrest.

"We were able to put 100 people into San Antonio police headquarters to start working leads for them," Combs said. "Also, there were leads from outside the area, so we had FBI around the country working leads and then we had assets back in Quantico working on video enhancements and some other things to try and identify the subject."

Marconi was a 20-year veteran who left behind a wife and three children.
