Two Grosse Ile (Mich.) High lacrosse players accused of slitting a guinea pig’s throat and hitting it with a bat were arraigned on felonies today, authorities said.

Tanner Coolsaet, 18, and Michael Roth, 17, of Grosse Ile are each charged with two counts of felony animal cruelty – killing or torturing animals and conspiracy to kill or torture animals, according to the Wayne County Prosecutor’s Office.

They’re accused of bringing a box with the animal inside to a team meeting at 11:30 a.m. April 30 before a lacrosse game.

“Coolsaet had a knife and slit the guinea pig’s throat. Roth grabbed the guinea pig and struck it with a small bat. The animal died shortly thereafter,” according to the news release.

The teens were arraigned in Woodhaven District Court on the felony charges, which each carry a maximum penalty of four years in prison.

“The alleged facts in this case illustrate much more than a youthful prank or a pregame antic. We must take these cases seriously,” Wayne County Prosecutor Kym Worthy said in a news release.

Both Coolsaet and Roth posted $5,000 personal bond and are scheduled for probable cause conferences at 9 a.m. July 26, and preliminary examinations at 11 a.m. Aug 2. Their bond conditions include not consuming alcohol or controlled substances and not purchasing or acquiring animals or pets. They have a daily curfew set from 11:30 p.m. to 6 a.m., according to the prosecutor’s office.
