SAN ANTONIO — The Bexar County District Attorney Nico LaHood said on Friday that he will to seek the death penalty against Otis McKane for the 2016 death of San Antonio Police Officer Ben Marconi.

District Attorney Nico La Hood said he thought long and hard about this case, weighing the best options for the people, the police department and Benjamin Marconi.

"It had to go through a process," he said. "I wanted to make sure that because of the emotion and the heinousness of this crime against one of our very own law enforcement in our community that I did not overreact and make an emotional decision too soon."

The 50-year-old detective was shot near department headquarters, on Nov. 20, 2016, during a traffic stop.

Marconi died roughly an hour after he was ambushed, shocking the community where no police officer had died in the line of duty since December 2013.

A man was caught on camera walking into the department headquarters hours earlier - before getting back in his car, circling the building then stopping again right behind Marconi's vehicle.

That shooting set off a manhunt that brought agencies on every level together.

"Everybody using their resources, coming together, humbling ourselves, everybody, and just adding when we needed to," said LaHood.

Police arrested Otis McKane on Nov. 21, 2016, and he was charged with capital murder in Marconi's death.

When he was being taken to the Bexar County Jail, McKane apologized  shooting Marconi and said "I just want to see my son."  He blamed his act on “society not letting him see his son.”

McKane also apologized to Marconi's family.

"I lashed out at somebody that didn't deserve it," he said as he walked in handcuffs out of the police department in 2016.

McKane is still in jail, waiting for the trial that could determine whether he lives or dies.

"He will get his day in court and the result will be the result but his repentance or not repentance is not an issue between me and him or this community and him. This is an issue of accountability and the issue of repentance will be between in God,” said LaHood.
