Pasadena Lt. Chris Russ said 39-year-old Monica Avila was booked for investigation of attempted murder. Investigators said the brother of Avila's ex-boyfriend notified police there was a trespasser on his property at about 3 a.m. Thursday.

When the 44-year-old man went outside to talk to Avila, she allegedly tried to run him over with her vehicle and fled. Police spotted her a short time later and pulled her over. The lieutenant said Avila suddenly removed her urostomy bag and threw it at the three arresting officers, who were splashed with urine.
