EVE Online: The Sniper

My corp went out last night for our first team mining run. Two battleships, a destroyer (i think) a cargo ship and 2 mining barges. We did well in 0.5 space (safeish). So we got adventurous and went to 0.4 space (not safe). We found a whole load of valuable ore, so we started mining. 2 minutes in, I saw a red flashing square, and Gant (battleship pilot) yelled "Get Out!!" I warped to a station and was fine, while I heard the other members chattering about the bad guy. The destroyer went down, and Cappie said to meet at the stargate the went back to 0.5. We met there and headed to the gate. On the way, the bad guy showed up again and fired large missiles at us from 150km (a long way) off. I lost the barge (10 million worth of equipment, 5 million repaid by insurance), and Mejiityr lost the Iteron II cargo ship which belonged to the corp. Cappie said he couldn't even get a lock on the guy. So Cappie and Gant are experimenting with different equipment to try to prevent getting smakked by a sniper like that again.
