SAN ANTONIO -- During a manhunt for a the man accused of killing a San Antonio Police Department detective, the suspect got married.

The marriage record is just part of what KENS 5 has uncovered about Otis McKane, now charged with capital murder in Det. Benjamin Marconi’s death.

As McKane was arrested Monday night, the 31 year old spoke out.

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

The only custody case KENS 5 could find associated with McKane was filed in 2011. Bexar County public records also show a woman filed for a protective order against McKane in 2012. That same year, he pleaded no contest to a charge of assault with bodily injury to a spouse.

On Sunday, the day Marconi was killed, McKane went to police headquarters around 7 a.m., according to his arrest report. He talked to someone at the department about a child custody dispute. The report states McKane left the building.

Hours later, as Marconi pulled a completely unrelated person over for a traffic stop in front of police headquarters, police said McKane’s Mitsubishi Galant passed by his location twice.

Marconi was sitting in his patrol car writing a ticket when police said McKane returned and shot him twice in the head. McKane drove away.

Monday, McKane was married. According to a marriage license obtained by KENS 5, McKane married Christian Chanel Fields at 9:57 a.m. at the Bexar County Courthouse. When McKane was arrested, he was with a woman who has not been named and an unnamed 2-year-old child.

The arrest report also states the rims on McKane's car were crucial in catching him. The person who sold McKane the rims said the pictures, which were plastered all over the news, recognized them and called police to tip them off.
