DNA on water bottle leads to arrest of Scottsdale rapist - New York News | NYC Breaking News

New details have emerged in the arrest of a 16-year-old boy for two sexual assaults in Scottsdale. Police say he's admitted to both crimes. How did they track him down?

After bringing Danny Jackson in as a person of interest, Scottsdale police offered him a bottle of water while they questioned him.

He accepted and left his empty bottle behind.

They tested the DNA from that bottle against DNA collected from both sexual assaults in Scottsdale last month. It allegedly was a match.

On October 18, the first woman was sexually assaulted. She told police at about 11:40 p.m. she opened to her patio door to let her barking dog out and saw a completely naked black man standing there.

Scottsdale police say that man was 16-year-old Danny Jackson. They say he forced his way into the woman's condo and raped her.

The second assault was 6 nights later when Jackson allegedly entered an apartment through an unlocked screen door and attacked the woman who lived there.

"Everybody's been very relieved, especially I'm sure the people who lived on the ground floors around here," says Marilyn Koch, who lives in the neighborhood where the two assaults occurred.

Jackson was a student at nearby Chaparral High School.

The school made an announcement to students Monday stressing that none of the sexual crimes happened on campus.

Still, students we spoke to say they were stunned.

"Things like this just don't happen around here… it just hit home, a lot of kids knew him and had classes with him," say Haley and Kirsti Reinsch.

Jake Gitt had one class with Jackson and says he didn't talk to others and seemed like he wasn't "totally there."

On October 31, Jackson was arrested for criminal damage at the CVS Pharmacy on Scottsdale Road.

Investigators identified him as a person of interest in the sexual assaults and his physical description matched the suspect. When they interviewed Jackson about the criminal damage, he left his DNA on a water bottle. It was a match.

Detectives arrested Jackson on Friday near his home, which is right behind Chaparral High School. After some questioning, he allegedly admitted to both sexual assaults.

At least one victim picked him out in a lineup.

Jackson is facing 11 counts related to both of these attacks. He has prior arrests for identity theft and assault.
