Incident Report for Case #2010-112895

Incident Type


Incident Date

04/28/2010 - 9:43 PM


2100 block of Fordem Ave




M/H, 16 yrs old


Male, age 19, Madison


The final suspect being sought in a 2010 gang-related homicide has been found deceased in his home country: Guatemala. Until the time of his death, Billy Wenner-Say, age 27, was being actively sought by the MPD and the U.S. Marshals Service.

He was wanted on a warrant for Party To A Crime of First Degree Intentional Homicide. Mr. Wenner-Say, and others, were accused of killing rival gang member Antonio Perez, age 19, on Fordem Ave. in April of 2010.

The man detectives believe pulled the trigger also – like Mr. Wenner-Say - tried to escape justice. Mr. Arain Gutierrez was arrested in Cancun, Mexico, in December of 2012. He is currently facing trial in this case.

Three other suspects have already been sentenced for their roles in the shooting.

As this high-profile case closes, the MPD would like to thank the U.S. Marshals Service for its continued support in tracking down fugitives.

Details regarding Mr. Wenner-Say's death were not immediately available. However, an autopsy did positively identify his remains and indicated he had been shot.  


Yesterday, Mr. Arain Gutierrez, also known as Ivan Mateo-Lozenzo, possibly age 24, was booked into the Dane County Jail on a charge of 1st Degree Intentional Homicide.

Mr. Gutierrez is accused of shooting and killing a rival gang member, 19-year old Antonio Perez.

The suspect was arrested in Cancun, Mexico last December following a lengthy investigation by the MPD, the U.S. Marshals Service, and the Dane County District Attorney.

Mr. Gutierrez is scheduled to make an initial appearance in Dane County Court this Friday.

The MPD would like to publically thank U.S. Marshals for their continued support in helping track down fugitives like Mr. Gutierrez. Senseless gang violence will not be tolerated in Madison, and U.S. Marshals help ensure those responsible will not escape justice.

• The suspect and his associates were also young Latino males. According to information obtained during the investigation, comments were made to suggest that the shooting was gang motivated. After the shooting, the suspects fled the area in a white, boxy style smaller car, with black rims or no hub caps, rust around the rear wheels wells, and a small spoiler on the back. The vehicle contained 4 Latino males, and one female.
