HONOLULU -- The man police arrested in connection with the death of a toddler on the H-1 Freeway did not have a violent criminal past, according to court documents.

Witnesses said Matthew Higa, 23, threw a child from the Miller Street Pedestrian Overpass on Thursday at about 11:40 a.m. (Read more about the incident.)

Police arrested Higa on Miller Street near Prospect Street. They took him to the Honolulu Police Department's cellblock.

He was seen rocking back and forth just before police took him out of the car. He was dressed in medical scrubs with the bottoms cut off and slippers.

He yelled into a KITV microphone moments after he was brought into HPD's cellblock.

"Thank you for everything," he yelled.

Court records showed Higa has traffic warrants and an arrest warrant for fourth-degree theft.

Records show Higa once lived at a house on Henry Street in Nuuanu next to some family members.

"He moved out a long time ago," one relative told KITV. "We're not close."

Several neighbors told KITV that Higa and his father were kicked out of this home by family members six months ago. They remember a lot of noise coming from the house.

"All the time I hear fight, fight, fight, glass broken," one neighbor said.

The suspect was a former employee of Papa John's Pizza in Nuuanu. Court documents show other employees requested but were denied a restraining order against Higa after he wrote bad checks for online pizza orders.

Higa was investigated as a possible driver in a three-car race that led to a fatal crash in August 2004, sources said. Higa was never arrested. One man died in the crash.

Police opened a negligent homicide case and turned the case over to the prosecutor's office, which declined to prosecute.

Higa is a 2002 graduate of Roosevelt High School.
