Authorities have released video showing a man wanted for fatally shooting his ex-girlfriend, a Waukegan native, opening fire on an Illinois State Police trooper and then physically attacking him.

An Illinois State Police trooper conducted a traffic stop around 10:45 p.m. on October 24 in the 1600 block of Toronto Road in Springfield.

Trooper Dakotah Chapman-Green made contact with Cristobal Santana, 37, of Chicago, who was in the vehicle.

Dashcam and surveillance video released showed Santana got out of his vehicle during the stop while armed with a gun.

He fired at least 10 gunshots toward Chapman-Green, leaving the trooper shot several times.

The trooper attempted to run but dropped to the ground a short distance away, the video showed.

State police said Santana chased after the trooper and physically attacked him, striking him repeatedly.

Chapman-Green was hospitalized with facial fractures, a skull fracture and a brain bleed.

“By the Grace of God, Trooper Chapman-Green survived this brutal attack,” ISP Director Brendan F. Kelly said.

“Police officers across the state take an oath to protect the lives of Illinois citizens and too often that means facing diabolical, hateful, vicious evil that no innocent human being should ever have to face,” Kelly said.

“We live in a free country, but there is no freedom without the law, there is no law without law enforcement, and there is no law enforcement without brave souls like Trooper Chapman-Green and those standing here with me today willing to do this noble, but dangerous work,” Kelly added.

Santana fled the area in his vehicle but was arrested hours later following a manhunt.

A police officer struck Santana with a squad car as he fled on foot from officers.

State police said Santana had been wanted in connection with the murder of Adrianna Lopez, 37, of Chicago.

Lopez was walking on the sidewalk in the 5400 block of South Narragansett Avenue in Chicago around 9:30 p.m. on October 22.

The Chicago Police Department said a “known suspect” approached in a dark-colored SUV.

He fired multiple shots at Lopez, striking her 10 times, as she was returning to her home.

Lopez was rushed to Advocate Christ Hospital in critical condition and pronounced dead, police said.

Lopez previously had an order of protection against Santana, who was her ex-boyfriend, according to her family.

Family members of Lopez, some of whom reside in Waukegan, had desperately sought Santana’s arrest on social media.

Norma Lopez said her sister’s life was “cut short.” She was a special education teacher for Chicago Public Schools.

The Sangamon County State’s Attorney’s Office approved two counts of attempted first-degree murder, aggravated battery with a firearm to a police officer, aggravated battery to a police officer and aggravated unlawful use of a weapon against Santana for the shooting of the trooper.

The Chicago Police Department has not yet announced charges against Santana in Lopez’s murder.
